Darren Collison makes the most sense by far. New Orleans has Chris Paul, and it makes no sense to have a player as talented as Collison as their backup PG. After his outstanding rookie season, his trade value will never be higher, and the Hornets need to take advantage. Collison proved that he can produce when given starter's minutes, and the Hornets would be holding back his delevopment by not trading him.
George Hill isn't going anywhere. Tony Parker will be traded before George.
Mike Conley is the Grizzlie's guy at PG, and won't be traded unless they get an obvious upgrade at that position.
Devin Harris lost my respect by losing so many games as the teams best player. I don't really want a shoot first PG either. A better version of TJ Ford.
Raymond Felton simply hasn't panned out as a quality starting PG for the Bobcats. Compared to the other PGs in his draft, Chris Paul and Derron Williams, Felton has underachieved. He has his moments, but I don't really know if he is that much better than Ford.
Ty Lawson could develop into a quality PG, but I don't think that Denver is going to give up on him after his rookie season. Billups is getting older, and Denver may view Lawson as their PG of the future.
Monta Ellis is the best player of this group, and I doubt that GS will trade him.
