He's the same player he was 3 years ago.
I disagree to a point - When he was originally recruited he couldn't have wildly expected to get all the playing time he's getting now. He's also a better jump shooter. Other stuff, I agree, hasn't improved. But he's in a good spot here. There is no reason for him to transfer. He's trusted by the coach (much to the chagrin to many on this board), and he gets the green light while he gets tons of playing time.
What complaint can he possibly have?
Improvement is just as much up to the player, if not more so, than on the coach.
He shouldn't transfer, it'd be idiotic of him (other than if he had true family matters to be near back home for) .
He should stay here, finish his degree, enjoy NYC and hoist up up lots of ill-advised threes and dribble around a lot.
