Pinnock is somewhat underrated, actually. Initially I thought Pops Mensah-Bonsu was their only draft prospect, but Pinnock is a guy who is capable of attacking the rack and filling the stat sheet especially in the steals category. He's quite athletic, but the downsides are that he's 6'5", doesn't have the best decision making and he's a good jumpshot away from the league. Still, he can afford another year and with his athleticism and nice guard build, he will get some looks in the mid to late 2nd round in the 2007 draft.
Carl Elliot is quite athletic, but not much of a draft prospect. Another year would be good to see what he could do.
As for Pops-Mensah Bonsu, he's basically wiped himself out of the draft picture with his injuries, not to mention he didn't improve all that much this year. Yeah, he's uber-athletic, but that's all. He'll be Olumide Oyedeji--out of the league.
