Pierre Jackson is one of the best players in college basketball, but not a very good pro prospect.
If D Thomas is available in the 2nd round, that'd be a solid pick. He'd give much better offensive production initially than most others in the class. Of course he'll never be a solid NBA defender, but there has to be a reason if he's a second rounder. I think he'll have a big year though, and someone will take him long before the second round.
