Yeah given that it is a Thompson driven stance that is preventing his buyout I don't see it happening. He's not giving up any money, so there is no reason for the Cavs to buy him out at full contract value.
He might be solid enough in matchups to move the needle, too many teams can play Kanter off the floor especially with his hip injury.
Instead we're counting on Kanter getting healthy, Grant, and hopefully Time-lord.
