Maybe trade Sasha for a 2nd rounder or something to free up the money to sign someone else, but, regardless of what the ownership would want, I'd feel silly waiving a guaranteed contract after one game.
I am not big fan of Sasha, but.....lets be honest. He was just as effective as Marquis (not) when defending Melo. He has an injured wrist that he is still wearing a brace on (left?). He was only in the game as a starter to play defense, which he did. No shooting or scoring was expected of him, they never even ran a play for him and he was open numerous times. I saw plenty of effort and he ran the floor well. The spacing he provided on the wings didnt hurt on Rondo's fast break layups.
This guy is an 11-12th man on our roster at best but not someone we need to cut this early. If his wrist gets healed up he is a dangerous jump shooter that plays defense with effort. I give Marquis a slight edge over him as a rotation guy and if Pietrus is healthy enough then Sasha may become our 14-15th man if he doesnt get his shot back. Until then I keep him unless we get a shot at a truly productive, rotation level big.
Then combine him with someone in a trade.
