Whither Marion?

What happened to this guy? He's a four-time All-Star and two-time All-NBA third team member ... but so far this season he sucks. He didn't like being the third star in Phoenix, and now he gets to play with another megawatt talent in Miami and be the second star. But his numbers are significantly down in every category. One would think that he would turn on the juice to secure a rich new contract. Is he partying too much down there?
