Omri Casspi has done a lot of good in a short time with the Rockets.

But he isn't satisfied and probably never will be. The small forward spends a lot of time looking at everything he has done wrong and working on the things he can correct.

He has been an offensive spark for the Rockets in all three preseason games this season averaging 16.7 points off the bench.

"I really need to get better on defense" he said.

He has had 19 rebounds in the last two games.

"I missed some rebounds in the first game though" he said.

He is shooting 50 percent from the 3-point line.

"I missed a couple of shots I can make" he said.

Casspi is a perfectionist when it comes to his game and that is making him one of the Rockets' best weapons.

"I am the guy who always looks at the bad things" Casspi said. "I am never satisfied with what I do. Every game I watch tape right after. I am always trying to get better."

He is turning heads with his work ethic and game performances.

In the preseason opener against New Orleans Casspi was 9-of-10 off the bench scoring 20 points and waking up the Rockets on offense in the final two quarters.

He followed that performance with 6-of-9 shooting from the field 17 points and 10 rebounds against Indiana in Manila Philippines last week. On Sunday in Taipei Taiwan against Indiana he had 13 points and nine rebounds.

McHale impressed

"He has been playing great has been rebounding the ball so well and hustling all the time" coach Kevin McHale said. "There is nothing not to like about what I have seen from him so far."

Casspi who had played with Maccabi Tel Aviv Sacramento and Cleveland before signing with the Rockets in July said he feels like his game fits in Houston where the Rockets' fast-paced read-and-react offense puts him in his comfort zone.

"We run" Casspi said. "It is pretty much who I am. I run. I have always wanted to be the first guy down the court sprinting the court not taking any plays off."

McHale said Casspi picked up the offense quicker than most players. McHale wants to see improvement on defense from him but said he isn't worried that it will come.

"He will pick it up" McHale said. "He is getting better all the time."

In his first year in the NBA in Sacramento during the 2009-10 season Casspi had a good start. He played in 25 games averaging 10.8 points in roughly 25 minutes per game. Last season in Cleveland Casspi played about 11 minutes per game and averaged 4.0 points.
