I think he's clearly going to be a center in the NBA. I don't see him being able to play much as a 4 due to lateral quickness limitations. For a center, he's undersized. Surprisingly, that hasn't affected his ability to block and alter shots much as he has really good instincts and positioning. However, he has struggled to rebound as a center. Also, he gets taken advantage of when he switches onto quicker players. Offensively, he's displayed a lot of skill, primarily doing center-type things, DHOs, post-ups, but he's also been very good off the dribble. He would fit in great on this Spurs team on offense. I think his ability to play in the NBA is clear but his size as a 5 and lack of lateral quickness is going to limit his ceiling.
