Great trade by the Pistons. Nazr is decent but not worth his contract. Joe D fixed the obvious mistake he made when signing Nazr. Plus he got Brezec and Herrmann who both have decent potential. But even if they both do nothing, it's still a great trade to get rid of Nazr's contract.
Nazr's one true redeeming quality is his ability to rebound. He's actually one of the better rebounders in the league this year -- far better than anyone on the Spurs. But he's sloooooooow and supposedly the Bobcats were trying to be a run and gun team this year.
