If Blatche is serious about ever doing anything positive in the NBA, he will choose a team that gives him the best opportunity to reach his potential and achieve something besides ridicule and a 36% winning percentage.
From what I understand, if no amnesty claim is made for him, whatever money he's paid will be deducted from his Wizards' deal. Signing for the minimum is in his future if not claimed.
Blathce has had issues with KG, but playing next to him on a team with the Cs' culture and strong coaching is the best thin for him. Unfortunately, Blatche seems to be the kind of person who will screw things up regardless of situation.
Even with his history, if he agreed to at least try to buy in here, I'd prefer Blatche over Sean Williams.
