Rapid Reaction: Mavs 102, Nets 89

How it happened: The Mavs beat up on a bad team, which is what Western Conference contenders are supposed to do.

Depth was the biggest difference between the Mavs and the 6-17 Nets, who lost point guard Devin Harris to a shoulder injury in the first half. The Mavs’ bench outscored the Nets’ reserves by a 52-24 margin.

Co-sixth men Jason Terry and Shawn Marion combined for 33 points, with Marion making all but two of his 10 shots from the floor. Backup point guard J.J. Barea matched his career high with 13 assists. Backup center Brendan Haywood was also a force, scoring nine points and grabbing eight rebounds in 18 minutes.

The Dallas starters should have been able to rest comfortably for the entire fourth quarter, but they let the Nets back into the game. A 21-point lead was slashed to five late in the third quarter, before the Mavs apparently decided to get serious and prevent Avery Johnson from sneaking away with a win in his American Airlines Center return.

What it means: The Mavs extended their NBA-best winning streak to 11 games. Five of their last seven wins have come by double figures.

Play of the game: Jason Kidd grabbed the rebound off a missed New Jersey jump shot and pushed the ball hard in transition. Shawn Marion filled a lane to the right and got fed the ball two steps from the bucket, finishing with a tomahawk slam with 3:44 remaining in the first.

Stat of the night: The Nets have never won in the AAC. The Mavs are 10-0 against New Jersey in this building.
