He must shoot better. He was recruited to score inside and out. The inside piece is improved, slightly. Defense, similarly (was dreadful last year). But he's knocking down little from outside other than unchallenged 15 footers. And, IMO, if he's to rise to the level expected of a guy who was a #2 on Scout.com's 2008 recruit ranking, he's gotta improve his foot speed 100%.
BTW, another #2 on that same Scout.com listing was Kemba Walker. Comparable performances by these two, today?
