Is Detroit really going to go with a Calderon-Knight backcourt, and force one of those two to play out of position? It doesn't make sense to me.
Detroit should just look to flip or buy out Calderon. He doesn't fit the roster in the short term, and he can only complicate the development of Knight as the Pistons PG of the future.
Two trade ideas for Detroit: to Dallas for Kaman, or to Utah for Mo Williams. Both those deals save a little money this season, and have no future cap implications. Perhaps Detroit could wrangle some additional sweetener out of the deal in the form of cash or a 2nd rounder. And then flip either Kaman or Williams for another, cheaper expiring contract.
