Forman must have already talked to Butler about this. Otherwise, there is no way he could say something like that to the media without drawing ire from Butler's camp. Not sure why he would say that, anyway-- can't possibly help his bargaining position to look so motivated.
I'd offer the Bulls #3/4, Bkn '18, Rozier, Young, and Amir. I think we could make it work with four good guards on the roster, as Smart has been playing a lot of 3 anyway and Butler is capable of it as well.
