From what ive heared though the grapevine, Patrick should actualy be one of the hardest workers right now together with Perk' and they are rumored to be working overtime every night after practice to get better at each others game and when were the last time anyone heared any reports from Doc or the Celtics commententing on Patricks lack of effort? i havnt seen one in a long time now.
Patrick has incredible gifts when it comes to playing basketball but he has suffered being a young guy under Don Nelson, in Boston he isnt being treated as a doormat by his teammates and the Celtics wont give up on him and let him root on the end of the bench like the Warriors did and you can see that by the commitment by Kevin and Perk both in timeouts at game time and what little we hear from practices.
Im most likely one of the very few to belive this on this board but i firmly believe we will see something most didt expect next year from Patrick, this year he wont have an impact as the psychial aspect of his game has not been tended to when he were with the Warriors and i scratch that down to a bad enviroment for young players, especialy bigs.
Edit: Just try to be in Patricks shoes during his tenure with the warriors? that must have been a living hell to endure that kind of treatment from both your teammates, coach and orginasation and its one of the arguments i hold on to when passing judgement on Patricks work effort, i do belive you would have seen a different O'Bryant had he come into this league with a team who actualy gave a [dang] about him.
