I saw Royce White when he was in HS. His team played in a tourny at Fordham. He is incredibly athletic. I see him more as a PF. I Think he will be a very good NBA player. As has already been stated, Moe needs to tighten his handle and improve his jumper and he will be fine.
I am a big fan of Perry Jones' game. If he can give good effort every night, he will be a great pro. Terrence Jones is a beast. He, too, has to bring it every night. Harrison Barnes needs to show more consistent effort and focus.
All these guys were highly rated recruits for a good reason. I don't really see any of them being a bust.
