The Bobcats are one of the worst teams in the league right now. Only second to Minnesota. Even a team like Toronto or the Clippers are better.
DJ is not a starting PG in the NBA. I want you guys to jot down a list of every starting PG in the NBA and then do a draft. Where would DJ be drafted? He'd be one of the last point guards taken. This team's embarrassing play isn't solely DJ's fault, I'm just illustrating that he is NOT the PG of the future for this team. He's a solid bench player, at most.
I think the main problem is a lack of overall talent. I don't like the way this team has been pieced together. Crash and Jax make one another redundant. Mohammed wouldn't even be a bench player on some teams, let alone a starting center. Letting Felton go and trying to replace him with DJ looks foolish. Trading away Chandler looks foolish (especially when your team is trotting out Mohammed). Kwame, Livingston, etc. are misfits, journeymen, draft busts, and many other things that pollute the bench. Larry Brown has checked out because a) he doesn't want to be here and b) he realizes that this team is one of the weakest teams in the league in terms of overall talent.
