Now let's see if the league wide Myth of "Teams Win, when Marbury leaves" theory lives on... should be interesting
If they can't find anyone willing to trade for him, at the very least for his expiring contract, maybe it's best to just buy him out now and cut him loose so that both the Knicks and Marbs can move on from all the drama they caused eachother.
He can still be a role player, so it's not like he won't find work. None of us know how serious his injury is though. After Steve Francis, many teams might not want to even take a chance on him, given his lockeroom reputation.
I say he should sign with Detroit. Flip and him get along well, and there is too many strong personalities in Detroit to allow another "Phoenix Incident"
