I don't think it's a good thing that KG's suspended. Gives Miami a solid chance to steal a game in Boston. The idea that this might fire up the team and get them to perform at a high level from the opening tip (and still win the game) is trying to find a silver lining from this incident. No problem with that, it's always worth looking for a silver lining.
One thought though concerning KG's replacement: it wouldn't surprise me if now that Scal will be active, there may actually be a chance Doc starts him to chace Beasley around and that will let Doc keep the current bench rotation. Not saying Doc will do this, but it wouldn't surprise me either.
