I'm a fan, if he's there at 16 he is who I think we should pick.
He must not jump very well because he was never tested for vertical at the combine (which indicates his agent probably told him not to do the vertical testing).
His vertical agility isn't great, but I think that is because he is getting used to his body after having a big growth spurt in HS. He has a fairly high body fat percentage of someone with his body type. I feel that he will get in better shape in the league and show better athleticism.
Looney is going to be a risk, who takes a while to develop. Once he does develop, I see him as a perimeter oriented 4 that can clean the glass, block shots and switch onto some 3's.
