I said it before that Rooks is legit center and would be drafted (possibly first round) if this was the NBA of 1995. I'm sure Chill knows him well and the only question about him was consistency and whether that's mental, physical or the PAC-12 style of play I don't know.
Re: Diarra... I got to the SMU game early and watched warm ups and thought Diarra was the most explosive big we had based on some drills and a lay up line. No one would have guessed he was hurt and I really believe the Montrez Harrell comp is legit from an athletic stand point. Whether he becomes a comparable player, in my mind, is a matter of will, luck (no more injuries) and hard work.
