In all reality, I expect Miller at least to cool off a little, but I think that we're seeing what he's capable of right now. I don't think he'll necessarily be able to do it game after game night after night like this forever, but he's showing that he can take over games and that he's putting the entire thing together finally. I'd expect his play going forward to be closer to this than where he had been, though maybe not this good night after night.
McD has done this before and he's doing it again. Feeling healthy, team is clicking a little more and he's not running around trying to play for two guys. Keep him with a good partner, whether thats G when he's playing well or someone else when G struggles and this is what he'll do.
