PBT says Brandon Jennings available for trade. Would trade #4 for him in a heartbeat.
PBT also says LaMarcus Aldridge wants out of Portland. Acquire him somehow, then I would feel much better about drafting a player like Cody Zeller.
fwiw, Zeller would be a good pick for New Orleans. I know they need a PG, but if you pair Zeller with another big man, his production would probably increase. I just don't trust Zeller as the main inside player on a team. Especially a team like the Bobcats.
