The Thunder has lost four of its past five games and six of the past eight. And following tonight's game, Oklahoma City will travel to San Antonio to face the second-place Spurs on Tuesday before hosting Portland, Indiana and San Antonio and traveling to Denver.

"We play against pretty good teams, playoff teams most of those games," said Nenad Krstic. "We just need to look to get better, especially these next two games against Boston and San Antonio on the road. We can use these games to see where we're at right now."

COLLISON ONE OF BRIGHT SPOTS

Forward Nick Collison has been one of the Thunder's lone bright spots the past two weeks, averaging 11.8 points and 8.8 rebounds the past five games.

"I've just been a little more aggressive," said Collison after a team-high 21 points Friday at Toronto. "I've been looking to score. I'm shooting the ball a little bit more. I think I'm anticipating when shots are going to be there and looking for it better than I was earlier in the year. So it's just the mindset of looking for my shot more."

Coach Scott Brooks said he doesn't expect anything different from Collison.

"He's a hard-working, intangible, winning Basketball player. He brings it," Brooks said. "He doesn't play to score. He plays hard, whether you play him 15 minutes, 20 minutes or 40 minutes, he's going to give you everything he has. I love the way he plays."

BALL MOVEMENT THE KEY

The Celtics are the second-best defensive team in the league, allowing just 92.7 points per game, and the key to beating the defending champs is teamwork.

"They're so good defensively, we have to really move the ball," Collison said. "We can't let the ball stick in hands for too long, otherwise it's impossible to score against them. You've got to be able to move them side to side, and make that defense work in order to get buckets against them.

"Hopefully, we'll come out ready to play. I think we will. It should be fun. We'll just play hard and see what happens."
