Sorry Celts fans, but if you pick up this guy, you can kiss your chances of repeating goodbye... he's been a cancer everywhere he's been, and if he comes in I think it will completely screw up the chemistry they have in Boston.
100% false.
A backup guard isn't going to mess with the chemistry of a championship team. Especially, when there would be no qualms whatsoever with letting him walk.
It's all on Marbury. If he wants to buy in and play, fine. If not, then he's gone. It's no risk, high reward with bringing him in.
