Denver took control with a 21-5 burst late in the third quarter, turning a flurry of Rockets' turnovers into easy baskets. Lawson said the Nuggets noticed a lapse in the Rockets' defense as their mistakes mounted.
"They're high-scoring and they love transition, but they don't like guarding," said Lawson, who also had seven assists. "Whenever they scored, or even when we got the rebound, we played in the third quarter to push it and try to get easy points. They didn't really run back too much and that's what we did."
James Harden scored 23 points but committed seven turnovers, and Omer Asik grabbed 13 rebounds for the Rockets. Houston coach Kevin McHale took point guard Jeremy Lin out of the game with 3:27 left in the third quarter, but the Nuggets continued their surge.
JaVale McGee turned in the highlight of the night, flipping the ball off the backboard and then dunking the putback with one hand for an 80-64 lead.

The Rockets have lost eight of nine.
"I think, right now, we are low on confidence, there's no question," McHale said. "You can see it with our guys and we're going to have to pump `em up and get `em believing again."
McGee and Andre Iguodala scored 14 points apiece for the Nuggets, who've won eight of their last 10 games. Denver shot 55 percent (22 of 40) and outrebounded Houston 21-16 in the second half.
"We've just got to keep playing like that," Lawson said.
Lin, meanwhile, watched the fourth quarter from the sideline for the second straight game. McHale also yanked him at the end of Monday's 100-94 win in Charlotte in favor of newcomer Patrick Beverley. Lin is 7 for 24 from the field in his last three games, but McHale downplayed his benching.
"Jeremy's fine," McHale said. "We're just looking for some stuff, it wasn't anything."

Harden got poked in the right eye trying to block Corey Brewer's 3-point attempt from the corner midway through the second quarter.
