"We dug a hole because we weren't defending well or we couldn't put the ball in the basket," Nets coach P.J. Carlesimo said.
The Rockets had 17 assists on their first 20 field goals. Parsons had eight assists by himself in the first half, matching his career high for a game.
"Our spacing was unbelievable," Parsons said. "It allowed more guys to penetrate, it allowed more guys to have open shots and we really moved the ball great."
Williams didn't score with Parsons guarding him in the second quarter, and Lopez went 1 for 7 in the first half. Houston outrebounded Brooklyn 27-15 and outscored the Nets 32-6 in the paint to lead 62-49 at the break.
Lin was back on Williams in the third, and the Rockets stayed comfortably in front. Brooklyn played better defense toward the end of the quarter and cut the deficit to 89-80. Williams missed a 3-point try and Carlos Delfino finished a fast break with a dunk early in the fourth to restore Houston's double-digit lead.
Lin sank his first two 3-pointers of the game to put Houston over 100 points for just the third time in six games. Harden converted a three-point play and drove for a reverse layup to give the Rockets a 113-98 advantage with four minutes left.
NOTES: The Rockets reinstated suspended rookie forward Royce White before the game. He's due to report to Rio Grande Valley, the team's developmental league affiliate, on Feb. 11. White, the 16th overall pick in the last draft, has been inactive all season while he worked on an arrangement with the team to balance his acknowledged anxiety disorder with the demands of the NBA schedule. ... Williams is the first Houston opponent to score 20 points in a quarter since Dirk Nowitzki scored 21 in the fourth quarter of a 117-110 Dallas victory last April. ... Harden missed a free throw, snapping a streak of 36 straight successful foul shots.
