At this point, I don't think he is bad.... but he is not good either. I think he very unpolished but has a good upside.
It is in his hands to get better this off season. He obviously needs to work on his lower body strength, post up moves and playing defense (without fouling and improve anticipating on where the ball is going). If he does, he will look alot better next year and alot of you who are bashing him might be eating your words.
