this year he pulled out of the draft, just like he's been doing the last 3 years. i think next year he will be 22, so he wont be able to withdraw his name for the draft.
as for his game, draftexpress has him being a "more talented PJ Brown" in the best case, and Jeff Foster in the worst case, if that tells you anything. his value has been going up and down after all this years of teasing the nba, and scouts know him pretty well.
given his situation, he will have to prove the world he has polished his skills on the offensive end, if he wants to be drafted high. people wont draft him on "potential" anymore.
