There are several ways you can look at this...My biggest dislike for players this decade has come in the form of their contracts. Suspect #1, for me, was LaFrentz. He signified the end of the Antoine era (which was EXTREMELY disappointing to me) and he carried a ridiculous 6 year/13 mill per contract. Runners-up include Wally, Blount, and Baker.
Then there were players that we kept, but we shouldn't have- Kedrick Brown (instead of J. Johnson), Forte, G. Green- could we have gotten more for those players if we had traded them earlier?
And then there were players that just didn't fit in- those listed above, as well as Mikki Moore, Olowokandi, Ratliff, etc etc...I am sure there are many many others and I don't hate these guys, they just made the decade a little less enjoyable.
