The Bucks are selling the organization so they are freeing up the cap space to make the team less expensive, also I think a S&T would be better for the bucks, because there is no way GP is going to want to be on a losing team that doesn't make the play-offs, Milwakee is RE-building, and expect a S&T for Payton, they'll be dumb to let him go for nothing.
I think if he signs a Sign and trade contract, the bucks can't keep him, get the contract states he is going to be traded. (I think).
Does anyone have information of those types of contracts???
