Dame doesn't look like he's even in shape or conditioned to be game ready. He looks kind thick, tbh. Here's a thought, though:
Why not lost him as doubtful or even questionable, but NOT PLAY HIM. The Spurs would have to game-plan and strategize for him on the court, but it would be a waste of time and they would keep wondering when are they going to insert him? Maybe would throw them off. Especially if we insert someone like Blake instead unexpectedly toward the end of the game and have him just fly around and harass the Spurs players and get steals and such. Could do the same with Sidy.
