Bang On. I would definitely start over with a core of Demar/Ross, Lowry, Jonas and Amir (Maybe Gay with a much more favorable contract). Ross and Demar stay if gay doesnt and if Gay stays, one of the 2 are traded for whatever nets the most.
Trade EVERYONE else for whoever/whatever you can get in terms young prospects or draft picks.
^^ this entails that we indeed fire Colangelo because he wont do it, and I am not happy with Casey at all as a head coach, but would keep him around in a similar role that he had in Dallas (Defensive specialist)
