Towards the end of overtime in last night's Game 2 of the NBA Finals, the Lakers took the ball with about 27 seconds left and a 3-point lead. ABC's Jeff Van Gundy (or was it Mark Jackson?) argued that Orlando should foul immediately. I thought this was bad advice. If you foul an 80% free-throw shooter, then there's a 64% chance that he'll make both shots and you'll be down by 5 points, and a 32% chance that he'll make only 1 shot and you'll be down by 4 points. There's only a 4% chance that he'll miss both shots and you'll have a chance to tie the game! My advice would be to try for a defensive stop and get the ball back. Granted, as Van Gundy observed, if the Lakers simply held the ball for 24 seconds, they would leave Orlando with only 3 seconds remaining to put a shot together. But they probably would not do that; rather, they would try for a score to augment their lead. This gives Orlando opportunity to either get a steal or a stop well before 24 seconds elapsed. It might not work, but the probability of success would probably be over 4 percent.
In the event, Orlando adopted perhaps a compromise strategy between my advice and Van Gundy's: they trapped the Lakers on the inbound pass (which was in the backcourt) and tried to effect either a steal or an 8-second violation. When this failed and the Lakers successfully advanced the ball across the half-court line, Orlando immediately fouled with 22 seconds left. They smartly chose to foul Lamar Odom, who is only a 62.3% free throw shooter (thus, a 14% chance that he would miss both, but an 86% chance that he would make at least one shot and make it a two-possession game). In the event, Odom made two free throws, Redick and Lewis missed three-pointers, and the ballgame ended as Jack Nicholson rose to congratulate the Magic's stars. A Coach Bhel would have handled things differently.

One Long Sleepless Night

Orlando, under previous general manager John Weisbrod, had a great summer in 2004, hauling two good draft picks in Nelson and Howard, and signing Hedo Turkoglu as a free agent. When Smith took over in June 2005, though, the general tenor of team management turned awful (or offal?). Orlando’s 2005 draft pick, Spanish center Fran Vázquez, refused to leave Europe despite earlier americophilic statements, and 2006’s draft pick, college yeoman J.J. Redick, proved to be a small and jittery shooter in the pros. In place of Vazquez, Orlando could have taken Danny Granger, Nate Robinson, Jason Maxiell, Linas Kleiza, David Lee, Monta Ellis … or if a center Smith coveted, Andray Blatche and Ronny Turiaf were available. In Redick’s stead, Orlando could have chosen athletic off-guards like Ronnie Brewer or Thabo Sefolosha. A host of point guards, including guys now manning contenders including Rajon Rondo, Jordan Farmar, Shannon Brown, and Kyle Lowry, were available in '06 as well; it would have been nice to have a feisty backup when Jameer Nelson was injured in February 2009.
Smith had a fine 2007, picking up Rashard Lewis and Marcin Gortat as free agents. However, he blundered quite a bit in trading Trevor Ariza, a skilled wing defender, to the Lakers for Brian Cook and Maurice Evans, neither of whom provide any of the oomph that T.A. does. To be sure, Ariza never showed any aptitude for three-point shooting or steals in the early part of his career, and he has burnished those skills in Los Angeles through extensive and patient practice. Still, Ariza was too athletic to discard so quickly. The 2008-09 period also worked out well for Smith, as described here: he drafted Courtney Lee and signed Mickael Pietrus and Anthony Johnson; later, he acquired Rafer Alston by trade when Nelson injured his shoulder.
I think this story illustrates that blunders in roster management are easily fixable. If Ariza were still on the roster, Smith would not have had reason or financial room to sign Pietrus; if a young PG like Farmar were understudying Nelson when the latter got injured, Farmar would have been thrust into the starting role, which frankly would not have got them to the Finals. (And acquiring Brian Cook later helped Smith acquire Alston.) It would have been nice if Fran Vazquez decided to play Stateside, but Marcin Gortat ably fills his role. But, but! — not all general managers are able to cleanse their errors. Whether out of misguided loyalty, unreasonable optimism, or a refusal to recognize one’s own poor judgment, many GMs choose to stick with their bad moves for far longer than is justified.

Kobe's Shameless Self-Promotion

"I rank this right up there with some of the biggest road wins we've had since I've been a Laker. Because in the past, we always had guys that had a lot of experience. Robert Horry, Rick Fox, Ron Harper, they've all been through this before. For our guys, this is brand new."
To me, this comment reveals that Kobe is very much aware that he is badly losing "the best baller in the world" debate to LeBron James. Part of the rationale for the emerging consensus on Lebron's supriority is that LeBron's and Kobe's teams have similar records but Kobe is doing it with another superstar (Pau Gasol), a borderline all-star (Lamar Odom), a future all-star (Andrew Bynum) and a strong bench, whereas LeBron is doing it with guys who have no business being on a championship contender.

The Lovers, The Dreamers, and Me
If you find yourself asking “Is that guy white or black?” (see: Shane Battier, Blake Griffin, Jason Kidd, Delonte West, Aaron Williams, Deron Williams, Mike Bibby, Jordan Farmar), the answer is almost always “he’s half and half.” Why is this complicated or surprising? Hey, it's 2009. Yet I hear this question all the time on internet discussions and, especially, in casual conversation from some close to me. Apparently "part this, part that" is not a psychologically salient category for many people: every human object of inquiry must be deemed one or the other. Of course, even Americans who phenotypically appear undeniably of either European or African descent probably have a little bit of ancestry from the other group.
(Being half one thing and half another, I hope I, Bhel, am insulated from charges that I am an obsessive racialist by dint of making these observations.)

Oompa Loompa, Doompadee Doo
Now, the raw proportion of all NBA games across the land, across years that go to OT is probably no more than 5%. To the extent you know that two teams are evenly matched (and Chicago and Boston minus Garnett certainly are), you are probably on relatively safer ground to predict that the game will go to overtime. But I would think that for these even-steven Bulls and Celtics, the most prudently correct answer to the question “Will the next game go to overtime?” is surely “No”. So over half of poll-takers got it wrong, no?

At first glance, this looks to me like an example of the representativeness bias, whereby, e.g., if you ask a poll respondent, “Who would you more likely find in a library: (i) a woman, or (ii) a middle-aged woman environmentalist with glasses?” many respondents will choose the latter because it sounds more quintessentially library-esque. But, of course, back in the real world, maybe 55% of library patrons are women, while about 3% are middle-aged bespectacled tree-huggettes. People don’t handle probabilities well. An overtime game between the Bulls and Celtics feels more emblematic of that series, so people feel, however wrongly, that it will recur.
Perhaps my point is weakened because 4 of the first 6 Bulls-Celtics games actually did in fact go to OT, so out of that sample, it’s actually safe to predict extra minutes. But sometimes crazy shit goes down, just by fluke. It’s hard to believe that I should update my probabilistic expectation of overtime from 5% to 50%. What do the numbers say? Consider the following Bayesian probability formula:
Such an updating would require that the proportion of Bulls-Celtics games out of all the overtime games played in 2008-09 is roughly ten times the proportion of Bulls-Celtics games out of all the NBA games played this season. So let’s consider some data. (I obtained all these numbers from the wonderful basketball-reference.com.) In 2008-09, there were 1230 regular-season games and 45 first-round playoff games, for a total of 1275 games, of which 70 regular-season and 4 playoff, or 5.804%, were overtime games. Out of all those 1275 games, the Bulls and Celtics played 3 regular-season games and 7 playoff games, for a total of 10 games, which was 0.784% of the 1275 games. Out of the 74 overtime games, 4, or 5.405%, were Bulls-Celtics games. So, the answer to my equational riddle up above is 5.405% * 5.804% / 0.784%, which equals 40.0%. Hmmm, maybe I was too quick to criticize the masses. 40% is pretty close to 50%, so predicting an overtime game based on the available data is not such a stretch. What if we make the analysis more precise by truncating the data set just prior to May 2nd, the date of Bulls-Celts game 7? This would put us in the position of a Bayesian observer filling out that ESPN poll just after game 6. This only deletes two games from our data set — Bulls-Celts game 7 and Heat-Hawks game 7. Now the correct Bayesian probability of overtime is 44.4% ! Wow! My initial supercilious dismissal of the silly plebes was way off. It seems that ESPN web users internalized the available observations quite well. 44.4% is still not high enough to predict that Game 7 will go to OT, but it's dang close.Meanwhile, the Atlanta-Miami series also seems to be indicative that the teams are evenly matched, but in a wildly different way. If Atlanta had won three games by huge margins and Miami had won three squeakers, then we might say that Atlanta is a better team and Miami has been touched by kind luck. But actually, the first six games were all settled by double-figure margins, and no game saw a lead change after the first quarter. We might say that the two teams are mediocre at best, and equally likely to suffer horrible mental holidays.

UPDATE JUNE 17TH: I just became aware of this June 10th blog post from Northwestern University professor of economics Jeff Ely. Check out the two Youtube animated graphs, showing the how the distribution of score differentials changes in the last 60 seconds of an NBA game, averaged over 12 years of data. Absolutely amazing stuff. The basic gist is that tie outcomes after 48 minutes are far, far more likely than 1-point victories or 2-point victories. You should also read the comments, which provide some speculative explanations for that data. I don't think this new information contradicts anything in my original post above.

Thy Tears Are Womanish
Back in the last month of 2008, we gaped aghast when TNT’s Inside the NBA spent the whole evening ragging on Kenny Smith after he commented approvingly on Terrell Owens’s buff body. It was amusing once, but for several hours? Ernie Johnson, who really should police juvenile hijinks on his show, was actually quite glad to toss in purportedly hilarious gibes of his own.
Last night’s (April 22nd) edition of Inside the NBA moved from subjugated fear of man-love to an hour’s worth of penis worship. Charles Barkley began the show by relating an anecdote about a job he held as a teenager, hammering tar off of pipes on hot summer days down in Alabama. Kenny giggled and labelled Barkley a “pipe beater”, and for the next sixty minutes, Ernie and Kenny used every opportunity to utter a ‘pipe’-related phrase, including “Pipe down”, “piping hot”, “down the pipe”, and “pipe dream”. Smith also subtly hinted at old wives’ tales about masturbation, including blindness and hairy hands. Seriously, I’m not joking; watch the video!
How much homophobia / homoeroticism is acceptable on this show? At this rate, will Johnson, Smith, and Barkley be comparing the size and aromatic quality of their excrement next week?

Kept In A Jar By The Door
We couldn’t find on Youtube the ad where a hopelessly smitten Chris Paul fan smothers his armpits into his buddy’s face. Right Guard’s website features a sadly static interactive exhibit where web visitors can learn a few factoids about Chris Paul, including his avid bowling habit. Isn’t that why Wikipedia was invented? In any case, the common feature of all of these advertising efforts is the absence of any active participation from Chris Paul himself (in addition to the rather odious presentation of Chris Paul's ’pits as something worth aspiring to). The association of a star athlete with, say, property insurance or underwear is always tenuous; the endorsement is a bit more convincing if the athlete feels like showing up for half a day of filming. (In the case of Dwyane Wade and his German mobile phone masters, how did he find the time to film all those spots with Barkley? Presumably they filmed them all at once last summer, but that must have taken at least three days with all the costume and scenery changes. That’s actually rather impressive for a guy defending against a bitter divorce and playing for Olympic gold.)
Anyway, Chris Paul needs a better agent.

In Which I Buck Your Wisdom
These vernal weeks are filled with teams that surely wish to prove they belong with serious squads and did not merely “fake” their way to 50 wins. Some teams finally find the right mix for a deep playoff run after several years of futility, as the Minnesota Timberwolves finally did in ’04. But, like the Raptors of 2000-2001-2002 or the Grizzlies of 2004-2005-2006, some teams realize that their core stars are just not championship-caliber, and they feel compelled to churn their roster and start over.
Of Denver, Houston, Dallas, and Chicago, I believe that the Mavericks have the greatest chance of making the conference finals or the NBA Finals. Needless to say, Chicago will probably lose in the first round against Boston, even if Kevin Garnett cannot play. Houston and its hard-working center, sadly, will probably lose again, playing Portland on the road and without a top-level point guard. Even if Houston got past the Blazers, the Lakers would likely eat them up; Houston lacks the size to defend Gasol, Bynum, and Odom. Meanwhile, I don’t have a lot of confidence in Denver. They did secure the second seed in the Western Conference, but they actually had as many wins as the third and fourth seed, and only six more than the eighth seed. Their putative leader, Carmelo Anthony, has never shown the defensive leadership or offensive explosiveness required for playoff laurels. And do you really trust Chris Andersen, Kenyon Martin, and JR Smith to keep their heads cool for six weeks of piercing intensity? That leaves Dallas, which fields a former MVP, a former MVP runner-up, and seven guys with NBA Finals experience (eight if you count their coach). The Mavs won nine of their last thirteen games, capped by a rollicking come-from-behind victory against Houston on the season’s denoument. I like the Dallas Mavericks to defeat the Spurs in the first round and the Denver-New Orleans winner in the second round. Of course, I still think the Lakers will beat Cleveland in the Finals, like every other pundit.

Ain't Never Caught A Rabbit
The correlation between defensive and offensive dominance seems to flow in cycles in this league. In the early part of this decade, the perennial best defensive players were Bruce Bowen, Ben Wallace, Doug Christie, Andrei Kirilenko, Ron Artest, and Dikembe Mutombo, who are not known for being dominating offensive forces. (Yes, Duncan, Bryant, and Garnett also showed up with regularity on the All-Defensive Team lists, but the league’s top scorers like McGrady, Iverson, Carter, and Nowitzki were nowhere near those votes.) Back in the ‘80s, the top defensive players were Paul Pressey, Sidney Moncrief, Mark Eaton, Bobby Jones, Michael Cooper, and Dennis Johnson, who were not synonymous with the league’s top scorers like King, Wilkins, English, Dantley, Gervin. (To his credit, Larry Bird made second team All-Defense three times.) In the ‘90s, top scorers and team leaders like Michael Jordan, David Robinson, Shaquille O’Neal, Gary Payton, Karl Malone, and Hakeem Olajuwon all routinely showed up on All-Defensive lists. On the other hand, other top scorers like Charles Barkley, Reggie Miller, Mitch Ritchmond, and Clyde Drexler were not defensive standouts, but then they also were not seen as offensive juggernauts who could will a team to victory in a tight playoff series. (Remember how many times the Pacers failed in the conference finals!)
We may very well be in a Golden Age of NBA awesomeness. These playoffs should be great. LeBron vs. Dwyane in the second round? LeBron vs. Dwight in the conference finals? Bryant vs. Paul in the conference finals? All are very plausible, given the likely seedings.

Papa Don't Preach
Miami Heat President Pat Riley’s first move of the voting year was his decision to demote himself from the coaching position and hire assistant Erik Spoelstra, who is young, smart, hard-working, well-liked by his players, and the first Asian-American head coach in the NBA. In June, Riley used high first-round and second-round picks to draft Michael Beasley and Mario Chalmers; he also signed free agents James Jones and Jamaal Magloire. Beasley and Chalmers have played well for rookies, though perhaps not quite at the level you might expect of a college player of the year and a Final Four MOP. Jones and Magloire have been injured most of the year and have delivered little. Later, in his biggest move of the year, Riley traded Shawn Marion, who was severely underperforming given his past achievement, for Jermaine O’Neal and Jamario Moon. This has been a decent move for the Heat; Moon mostly duplicates what
Donnie Walsh of the Knicks made several hits in 2008-09. First, he relieved Isiah Thomas of coaching duties and hired Mike D’Antoni, who averaged 58 victories during the previous four seasons with
Orlando GM Otis Smith didn’t do a lot, but his few moves were indispensable for the team. First, he drafted college senior Courtney Lee, who has shown poised defense and adequately drilled 3-pointers to keep defenses honest. Lee beat out three other veterans — Mickael Pietrus (an athletic wing player whom Smith smartly signed as a free agent from Golden State last summer for only $5 MM annually), J.J. Redick, and Keith Bogans — for the starting spot. Later, when Jameer Nelson suffered a season-ending shoulder injury, Smith quickly and effectively scrambled to replace Nelson at PG, using the few tradeable assets on his squad. First, Smith traded Keith Bogans, who was effectively the team’s fourth option at SG, for Tyronn Lue so that the team could have a proper backup point guard as long as Anthony Johnson needed to start. Later, he traded Brian Cook and Adonal Foyle, plus a future draft pick, for Rafer Alston, who immediately walked into O-town and began running the ship like Capt. Chesley Sullenberger. Even better, Foyle later returned to

Ultimately we had a tough time deciding among Ferry, Riley, Walsh, Smith, Warkentien, and Presti, but if we had a vote, we would deliver the NBA Executive of the Year Award out to Sam Presti for his patient, long-term planning. We can’t wait to see what he does next.

UPDATE May 3rd: Denver's Warkentien won the award with 9 of 30 votes. We consider this a fine choice, as we had him second on our ballot. Surprisingly, Oklahoma City's Presti only received one vote!

I'm Happy Just To Dance With You
Losing teams made a lot of lateral decisions that are hard to evaluate right now. For example, in
John Paxson of the Bulls selected Derrick Rose first in the draft, refusing to imbibe the honeyed vapors of Michael Beasley or O.J. Mayo, whose amazing scoring skills helped them appear more “NBA-ready” at the time. Rose, who leads all rookies in assists and ranks second in points per game and minutes played, has validated Paxson’s gamble. Paxson also made the curious decision to hire Vinny Del Negro, who had never coached basketball at any level. The Bulls have played .500 ball in VDN’s first season, which probably is a bit poorer than a more skillful coach could have steered the team, which features six former NCAA Final Four stars. Later, in February, Paxson traded Nocioni and Drew Gooden for Brad Miller and John Salmons. Salmons has been rock-solid for the Bulls; his March included 21 points per game, nearly 5 rebounds, and 50% field goal percentage, and the Bulls went 9-7 in that month. Paxson traded Larry Hughes for Tim Thomas, Jerome James, and Anthony Roberson, although this trade did not help the Bulls much on the court or on the P/L sheet; all three of the new contracts, which sum to about the amount of Hughes’s contract ($13 MM), expire in 2010, just as Hughes’s deal does. Perhaps the disaggregation of the $13 MM into more “modular” assets gives the Bulls more flexibility for future trades. Finally, Paxson jettisoned Thabo Sefolosha for a draft pick. This last one didn’t make much sense to me. With the loss of Hughes and Sefolosha, the Bulls only have three rotation guards: Rose, Hinrich, and Gordon. Gordon likely won’t be re-signed after this spring, and Hinrich probably should be traded so he can properly play a starting PG role elsewhere. Possibly, John Salmons could be a starting SG with Luol Deng on the floor to play SF, but that still leaves only two decent guards on the team. Sefolosha was, and could continue to be, a solid bench contributor, but now he is playing le beau jeu in
Since June 2008, New Jersey’s Rod Thorn selected Brook Lopez in the draft, then moved Richard Jefferson for Yi Jianlian and Bobby Simmons. He also signed free agents Jarvis Hayes and Eduardo Najera, who have been mostly inconsequential to the team. Lopez has been awesome, a steal at the tenth position in the first round. Had Thorn pulled off the rumored trade of Vince Carter for young talent or draft picks, he might be a contender for this award, but we simply cannot put Thorn near the top of the list, given the poor performance of Yi, whom some thought could become a Nowitzki-like freak. GRADE: B-

Yet, I wonder what the Blazers could be if, counterfactually, they had drafted even more smartly. So far Pritchard has scored several good moves: In 2007 traded Zach Randolph for Channing Frye and (the soon-to-depart) Steve Francis; in 2006 he drafted Brandon Roy, LaMarcus Aldridge, and Sergio Rodriguez; and in 2007 he drafted Rudy Fernandez. His choice of Greg Oden over Kevin Durant looks increasingly poor, though. Imagine the Blazers with Joel Przybilla sucking in rebounds at an insane rate and bodying up to opposing centers as their full-time center, and Kevin Durant pouring in points as their starting 3. And how can we forget the previous regime’s decision to trade out of the #3 position in the 2005 NBA Draft when Chris Paul and Deron Williams were on the board? Their eventual booty from that draft, Martell Webster, is not all that good, and only played about 5 minutes this whole season. CP3 would surely be an upgrade over Steve Blake. But of course, the draft is a crapshoot, and the jackpots of Roy and Aldridge are better than most teams ever do in a three-year period.
Houston General Manager Daryl Morey had a pretty good year — first drafting Joey Dorsey, and then acquiring Ron Artest, Von Wafer, and Brent Barry before the season began. He then lured Dikembe Mutombo out of retirement, and then, observing that Aaron Brooks was ready for a starter’s role at the PG position, he revivified the team’s PG play by trading Rafer Alston for Kyle Lowry and Brian Cook. I believe, though, that Morey’s year is notable more for what he did not do: he could have traded Tracy McGrady while his value was still high (before he bowed out of yet another season, this time with microfracture knee surgery). Morey may deeply regret his excessive patience with T-Mac. Morey also organized a “sports analytics” conference in March ’09 at MIT’s Sloan School of Management. We nerds at JPO adore any attempt to impose rigor on the fuzzy realm of basketball “analysis”, so he gets some extra bonus marks therefor. GRADE: B+

Let Her Cry
Sports websites like ESPN.com and CNNSI.com need to publish fresh content every day of the week in order to satisfy hungry readers who have grown accustomed to a steady stimulus of commentary. (Luckily, the same economic and ethical duties do not bind us here at JPO.) Every spring, a tested genre of prose is the “Awards Prediction” piece, in which writers size up the top players’ regular-season performances and predict (or recommend) which players will earn the NBA’s individual awards. One thing they almost never do is talk about who should win Executive of the Year – probably because, while the criteria for awards like Most Valuable Player or Most Improved are poorly defined, the standards for a good management performance are completely inscrutable.
To our view, a good executive is one who keeps his players and fans happy, builds a well-coordinated roster (including the right coach) that can produce quality play on the court, maintains a reasonable payroll with flexibility for future roster moves, helps his owner turn a profit, maximizes some discounted stream of present and future team success. (The precise discount rate is probably higher than a typical financial discount rate, given the frenzied myopia of sports fans.) Obviously these criteria are not precisely defined, and not always mutually compatible. Still, we will consider these rules as we evaluate performance from the past year.
Let us keep in mind, first, that the term of consideration for Executive of the Year begins with the end of the regular season in April one year, and extends to the same date the following April. In 2007-08, two general managers stood out for excellent work – notably, it was the two executives who sparked their churned rosters to the Finals. In the summer of ’07, Danny Ainge, top man of the Celtics, acquired Ray Allen, Kevin Garnett, and James Posey, and later signed Sam Cassell and P.J. Brown for the season’s stretch run. Plus, he drafted Glen Davis and Gabe Pruitt. Meanwhile, on the other coast, the Lakers’ Mitch Kupchak acquired Derek Fisher, Trevor Ariza, and Pau Gasol for next to nothing (the latter by using as currency Javaris Crittendon and Marc Gasol, both of whom had been drafted in the ’07 draft), and later signed the earnest D.J. Mbenga when Andrew Bynum went down. There were few other executives whose performances really stood out that year. Orlando signed Rashard Lewis to a long contract; the Hawks drafted Al Horford and traded for Mike Bibby; Rod Thorn ripped off Mark Cuban in the Jason Kidd trade; and Isiah Thomas (yes, that guy) drafted Wilson Chandler and traded nearly-immobile Steve Francis, plus the disappointing young strapper Channing Frye, for a useful asset in Zach Randolph. But, of course, none of these teams made much noise when it counted in the spring of ’08.
Ainge won the award, but Kupchak easily could have taken the prize.
Let us now turn to executive performances in 2008-09. First, to be thorough, what of last year's award winners? To save money in 2009-10 and 2010-11, Kupchak traded Vladimir Radmanovic for Adam Morrison and Shannon Brown (who has seen playing time at backup PG for the Lakers, supplanting Jordan Farmar); and Ainge decided to cut costs by letting James Posey sign with the Hornets, before drafting Bill Walker and J.R. Giddens and signing Stephon Marbury and Mikki Moore as free agents late in the season. These decisions were all probably helpful for the respective teams’ long-run health, but none was terribly consequential. Neither Walker nor Giddens have played all year, and Marbury really isn't that useful when Eddie House is available as a sweet-shooting backup point guard. These moves are barely worth considering to bury or praise.
This post will address terrible executive management for the 2008-09 award year; future posts will examine strong executive performance. The worst General Manager of the Year has surely been the Clippers’ Mike Dunleavy, who committed about $14 million per year through 2012-13 to Baron Davis, who is often injured and usually unhappy. Then he foolishly let Elton Brand get away. Then he acquired Marcus Camby as an ostensible replacement for Brand, though Camby is more of a skinny shotblocker, not a low-post beast like Brand, and plays the same position as center Chris Kaman (who is signed at $12 million per year through 2011-12). Camby is owed about $8 million in each of 2008-09 and 2009-10 – thus ensuring that the Clippers would have two seasons of an unbalanced roster. Pushing a bad situation into total entropy, Dunleavy then traded some spare parts for the notoriously defense-averse Zach Randolph, who is signed through 2010-11 at $17 million per season. It would have been better to let the contracts of Cuttino Mobley and Tim Thomas expire, rather than adding this wide load to the team. Now it’s April, and with 80 games done in the season and two left, the Clippers have won less than 25% of their bouts. GRADE: F
In Golden State, team president Robert Rowell and de facto GM Don Nelson traded Al Harrington for Crawford after Big Al developed a feud with Nelon; drafted freakish big man Anthony Randolph; let Baron Davis get away; signed Ronny Turiaf, an energetic shot-blocker; traded for Marcus Williams (who hardly played a minute all season, before being inexplicably released in March despite a guaranteed contract) after Monta Ellis wrecked his ankle; and gave a five-year free agent contract to Corey Maggette, who adds nothing that other GSW slashers like Ellis, Stephen Jackson, and Kelenna Azubuike don’t. Later, Nelson threatened to trade Crawford if he exercises his player option for 2009-10. The Warriors also alienated Monta Ellis by muttering about terminating his contract after his Moped-induced ankle injury. Though they may have that contractual right, it’s a non-credible threat; they signed him to a market-rate deal for a young budding star – why would they want to lose him? GRADE: E
In Phoenix, Steve Kerr continued his odd tinkering with (some would say destruction of) the roster, trading Raja Bell and Boris Diaw for Jason Richardson and Jared Dudley. He drafted Robin Lopez and traded for second-round draft pick Goran Dragic, and later signed Matt Barnes and Louis Amundsen as free agents. Unfortunately, Lopez is not as skilled as his brother Brook; Dragic struggled when featured as Steve Nash’s understudy; and Amundsen and Barnes are little better than the role players on any other bench. Kerr’s worst move was hiring Terry Porter to coach a defensive-oriented team when he lacked defensive-oriented personnel, especially after trading away Shawn Marion the previous February. And why would he then trade Bell, the team's only remaining good defender? He also should have known that a team full of veterans, many hardly younger than Porter himself, would blanch at following Porter’s authority. Firing Porter in February was an admission that Kerr has no clue about the direction of the franchise. Kerr has already admitted that a run-and-gun style cannot work in the playoffs, so what is the point of installing Alvin Gentry as coach? Perhaps there is something to just pleasing the fans for a couple more months and aiming for a playoff berth, but Kerr needs to seriously rethink his strategy this summer. If defense wins, then trade Nash, Shaq, and Stoudemire, who all will fetch serious value in the form of draft picks, and start over. You’re not winning anything in 2009-10 anyway. GRADE: D

Ain't Too Proud To Beg

My first thought upon reading this is that each team faces the same biases, averaged over the season, right? Even if there is a home bias for assist tallies, each team has 42 home games and 42 road games. Every team gets a diverse sampling of different arenas around the league. … But that’s not quite right.
Each team in the league has a different mix of opposing teams on its schedule. For example, an Eastern conference team, say Miami, plays 52 games against Eastern conference opponents and 30 games (two per Western team) against Western opponents. Of the 52 games against Eastern opponents, Miami plays four times against each of its four Southeast Division rivals (Atlanta, Orlando, Charlotte, Washington), and three or four times against all other Eastern teams. Now consider Atlanta. Atlanta’s schedule mix is roughly the same, except that they play Miami four times, and they don’t play Atlanta! Next, consider Detroit’s schedule vs. Miami’s. Detroit plays each of the other Central Division teams four times, which is pretty similar to Miami, which plays each Central Division team (including Detroit) three or four times. Detroit plays the Atlantic teams three or four times each, just like Miami does. Detroit plays each Southeast team (including Miami) three or four times, whereas Miami played all the non-Southeast teams four times. Also, Detroit plays each Western team twice, just like Miami does.
But a Western team, say Utah, plays each Eastern team only twice, and each Western team three or four times (each Northwest Division team, four times for sure). So the greatest discrepancy of schedule is between Eastern vs. Western teams, rather than any discrepancy for teams of different divisions within the same conference.
We can assume that the home statisticians of each team will be roughly equally friendly (i.e. very) to home-team point guards in assigning assists. The real variation, I would hypothesize, comes in how friendly the home statistician is to the visiting team’s point guard. Some may have a strong sense of fairness, while some may just say “Screw it.”

It is notable that of the top seven players on the league assists leaders list (or equivalently, the players averaging 8.0 assists per game or above), five play in the Western Conference. Now, perhaps this limited sample is not fair; ten of the top twenty players come from the East. Still, it is instructive to consider the gaudy end of the distribution. If there are more arenas in the West where the statisticians happen to be unusually friendly to visiting PGs like Paul, Williams, or Nash, then they could have an advantage in amassing assist stats compared to guys like Rondo or Calderon who spend more of their time in the East.
The obvious solution, not mentioned by the WSJ writer, is for the NBA to assign official statisticians to each game. Really, I don’t understand why this isn’t done. Teams could still track and collect their own stats privately, but why not have a neutral, central, better-trained body take charge of the statistics? We trust the federal government to collect unemployment data; we don’t ask a local Chamber of Commerce or the National Association of Homebuilders to do it for us.

I Can Show You The World
I was also puzzled at CBS’s decision to give free promotion during its segment on internet security to both Symantec and Google, both of which would be very glad to sell anti-badware products to the masses. Are there not academic or non-profit institutions tracking malware that could provide exactly the same neat-o demonstrations of security risks as the Symantec fellow provided? Why, I seem to recall the New York Times featuring a report by an internet security center at the University of Toronto just this very day.
Curious all around. I really and truly wonder whether David Stern, Eric Schmidt, and John Thompson (the CEO of Symantec, not the retired basketball coach!) will compensate CBS News down the road for 60 Minutes’ generosity.

I May Not Get There With You
To try to further unpack some of these notions, we here at JPO did some simple statistical analysis and uploaded our data to public Google Docs spreadsheets. We considered J-Rich’s stats for the current season with Phoenix (though the data is a bit abbreviated, as he has only played about 50 games with the team after being traded from Charlotte) and his 2007-08 stats with Charlotte, during which he played in all 82 games.
In both seasons, we calculated some simple correlations between various offensive performance metrics. Some of the correlations are obvious: if a guy scores more points or makes more buckets, then his team probably tends to score more points, and is more likely to win, so we expect a positive correlation. In evaluating the question of whether J-Rich’s taking more shots helps his team win, we focused in particular on the simple correlation between his FG ATT and his team’s win or loss outcome.
We found a weak 7% correlation in both seasons. Of course, causality is hard to interpret. This could mean that the team thrives when J-Rich shoulders relatively more of the scoring responsibility, freeing guys like Okafor or Steve Nash to do their thing. On the other hand (particularly with Phoenix) it could simply mean that the team thrives playing a faster pace, and more FG ATT by J-Rich is indicative of more FG ATT by all players on the team, and thus a higher chance of winning. These calculations would be easy, though we did not explore them due to lack of interest in gathering the data.
We also calculated the correlation between J-Rich’s field goal attempts and his field goal percentage in any given game. We found a 31% positive correlation with Charlotte, and a 17% positive correlation in his Phoenix tenure. So there is some evidence there that he is more accurate when he shoots more. On the other hand, this evidence could mean that his teammates are passing him the ball more because his initial shots on a given night were relatively accurate and they perceived he had a ‘hot hand’. Again, we could track this more precisely by gathering intra-game shot cart data and measuring accuracy over time within one game, but we really didn't feel like it.
We also computed J-Rich’s average FG attempts in wins and his average FG attempts in losses, and performed a two-tailed t-test based on a null hypothesis that the two averages are the same. Similarly, we computed J-Rich’s average points in wins and his average points in losses, and performed a two-tailed t-test for the null hypothesis that the two averages are equal. Basically, the difference was not significant at any reasonable level. Richardson’s points output shows a statistically significant difference (at a 10% level) in his teams’ wins vs. his teams’ losses, but we kind of expected that, as discussed above.

So in sum, I still have no idea what is meant by “he needs a lot of shots to be effective”. If he can’t do much other than score, why keep him on the roster? Someone more scrappy who can score less but do more other good stuff would be more valuable. J-Rich has by far the worst net plus-minus rating of any of Phoenix’s stars. Perhaps the secret of his “effectiveness” is more economic: fans come to see fireworks, not box-outs and extra passes.
