From everything I have read he wants to play badly. He has been engaged with the team during any chance possible (practices, timeouts, ect.). I think he is just as depressed as we are and was looking forward to the chance to lead a team.
Whether or not his own foolishness caused this situation or the 76ers exaggerated the timetable for his return has, will, and deserves to be debated. His want to play is something that is stupid to question.
