The Rockets got lucky tonight. This would have been an easy win for the Kings with just a little use of BBIQ. The Rockets did not have Howard. Clearly that is a situation when all your efforts should go to get the ball to DMC under the rim. If they double or triple team him, the rest of the guys have an easy task scoring big time.
The other basic fact is that Houston is a fast break team. They live out of turnovers and steals. So don't stand with the ball! The ball and the players without the ball must move constantly. Otherwise they will just intercept you and score fast. They are also a 3-point shooting team. Don't let the shooters, especially the guards, get the ball for open shots. Once they get to shooting it's too late.
How come DMC had the highest number of assists. Probably for the same reason that caused him 7 TOs. He was made to play the PG. Casspi could have 7 assists as well. He was really passing the ball nicely and giving some candies to others, but nobody converted. No a good shooting night for the Kings, but not intolerable.
The Rockets managed to get the Kings to play a game that they are not good at. Inexperience.
