They owe Brandon Bass the amount stipulated on his contract. Depending on the internal goals of the team, they'll play him more or less over the remainder of the season or until he's traded. He is not Josh Smith by any reasonable comparison -- potential talent, attitude, salary... bad comparison to a guy who is addition by subtraction.
I think Bass will go to a team that wants him by the deadline because he is a valuable role player. But if he doesn't, CBS and DA treatment of him will have zero effect on future FA's to Boston. I do believe the C's will be in the mix for quality FA's when they get a lot better. Unfortunately, weather will always be a negative variable when competing against LA, Miami and other warm/fun destinations. The "Brandon Bass factor" will be a non-issue.
