I wouldn't assume that; I think both are going 7.
I know I had said the Rockets had no shot to win this series, and I was dead wrong, but if Paul is too hurt to play, I don't see any way they win either of the next two. Plus, Game 7 is Memorial Day evening, a ratings bonanza and major showcase, so don't be surprised when Game 6 is officiated more tightly, which will prevent Houston from roughing the Warriors up. The NBA can always find a way to tilt the game with certain refs officiating certain games.
