I think all the guys from UNC are going to pan out better than most think, especially Ty Lawson if he can stay healthy. I'm no scout, but I'd say Danny Green has a good chance to become a roleplayer in the league, based on his versatility and defense. Psycho T might surprise some, but my gut says he's a career 6 pt/4 rebound bench guy. I only question Wayne Ellington, not too sold on him.
Darren Collison is someone who'll be a good value in the 20s - most likely a 9pt/5asst guy off the bench or a fringe starter.
