The Houston Rockets have struggled this season and Mike D'Antoni blames some of their issues on a lack of roster depth. 

"Obviously, it's a problem," D'Antoni said. "It's something that I know that the front office tried to address. They're going to do the best they can. No blame going around; it's just the way it is."

The Rockets played without Chris Paul (hamstring) and key reserve wing Gerald Green (ankle) in Wednesday's loss. In their loss to the Mavericks, Houston was outscored 65-25 in bench scoring.

D'Antoni expects both Paul and Green to be back for Friday's game.

"Then our depth is pretty good," D'Antoni said. "We've got everybody a couple of rungs up. We've got rookies playing as the sixth or seventh man. They should be ninth, 10th men. They would be OK every once in a while, but when you rely on them, it's tough. And it's not their fault. They're going to develop. Again, we're just going to have to knock on wood and make sure they stay healthy."
