It's very simple how to beat the Rockets in the playoffs. You take Tmac out the game and you win the series.
I think the Rockets have pretty much decided to concede the outside shot and protect the paint. Most of the time that works pretty well but if the outside shot is falling for the opposing team, the Rox are in trouble (like last games vs. Spurs and Suns). I suppose they do this to make-up for their lack of size. The Rox definitely need to move the ball better than they have been. The Rox seem to getting into the very bad habit of giving the ball to TMac almost every single play and wait for him to create. That ain't gonna hold up in the playoffs.
