Everyone talks about his weight, but the weight concern is just a sympton of the real problem, which is his conditioning. He needs to be in the kind of shape where, if called upon to do so, he'd be capable of playing 48 minutes in a game without losing too much. Not because he'll be asked to do so with any regularity but because he should be able to do more than just what is being asked of him.
No, the real concern with Sully, more than ANYTHING....is his attitude.
The weight/conditioning problems concern C's fans because they are worried that his guy has the talent, skill and basketball IQ to be an All Star. The question mark against him is that he doesn't have the right 'take no prisoners' attitude that you need in the NBA to be a great player and what the Celtics need from their big men in the front court.
He's beaten up his girlfriend, he's been late or missed practices multiple times, and he's had weight issues and injury concerns due to weight issues for his entire career in college and pros.
I love Sully and I think he gets more attention for what he hasn't yet become when he should get more attention for how [dang] good he is and how important he's been to the Celtics rebuild. But I understand why he gets a bunch of 'tude' from us armchair GM's and from the media, and it's because it frustrates fans to see him with all the tools/physical capabilities to be a top 30 NBA player and maybe even an All Star (in the Carlos Boozer/Paul Millsap vein) and not have the desire to put it all together.
The John Lucas camp is a great idea and I just hope he's still got some maturing left in him.
