We already have 2 undersized PFs in the roster. Why a third one?
I agree. He doesn't fit what we need. Sure he could play the three, but he wouldn't space the floor that well and be a defensive liability. At the 4, he isn't an enough of an upgrade over Powe and Davis to justify spending the money it'd take to get Minny not to match (likely the MLE or close to it).
If we're going to go the way of Boston retreads, I'd much rather see Delonte West who would stand as an improvement at the backup point guard position and a decent replacement to Posey/T. Allen backing up Ray.
