I don't know how much he can improve his game by coming back next year, but I think if he comes back next year, he goes higher in the draft. I don't really have much to back that up other than what I've read and seen on different internet sites that cover the draft. Most have him as a borderline 1st rounder right now at best, and everything I've seen for next year has him going as high as mid-late lottery and no lower than late first round. I think its best for him to come back. The only improvement I could see him needing to make is to become a little better offensively and develop a little more consistency on both ends. He had a a stretch in Jan. where his block totals were pretty low, and that dropped his stock a whole lot in the eyes of scouts. I disagree with the guy who said he doesn't have a position. He's a PF in the NBA. He may need to add a little weight (which is debatable whether he can do it or not), but he can be a solid bench player without adding a lot of weight, I think.
