The Mavs got a bit too comfortable with the large cushion and the Jazz found energy in forward Marvin Williams' hot shooting and some inspired backcourt play from reserve guard Diante Garrett, who didn't play in the first half. Utah got within eight points twice early in the fourth quarter and then trailed 90-85 with 4:41 to go.
"Biggest shot of the game," Mavericks coach Rick Carlisle said.
The Mavs weren't happy about allowing their big lead to slip away on the first night of a back-to-back when their starters seemed in line to get some extra rest.
"The key for us was probably from the get-go, getting a good start," said Mavs center Samuel Dalembert, who notched a double-double with 18 points and 12 assists. "We know with the other teams we have we can't let them get their confidence back up. We have to get them down from the very beginning.
"We did a good job in the second half. They came back in the third quarter when we were kind of slacking a little bit. They got the confidence back and made a run. The coach brought the starters back and we got the win."
DALLAS was led by shooting guard Monta Ellis, who scored 13 of his game-high 26 points in the first half when the Mavs shot 59.0 percent, poured in nearly half of their points inside the paint and turned 13 Jazz turnovers into 18 points.
Unfortunately for the Jazz, the hole they dug in the first half was just too deep to crawl all the way out. They got just 11 points from their starters in the first half, including no points from either of their leading scorers, forward Gordon Hayward and center Enes Kanter.
The things we talked about this morning in the shootaround and the things we talked about before the game, and we allowed them to get where they wanted to go. One thing we have to (do), we have to play with energy and a sense of urgency. I didn't think we had it in the first half."
Hayward was a game-time decision with a bruised right kneecap sustained in Wednesday's loss at New Orleans when he shot 1 of 17 from the floor. He finished with 13 points as did forward Derrick Favors. Kanter finished with just two points on 1-of-6 shooting.
"The way they were playing him (Hayward), I thought he was waiting for it to come to him. We need him to be aggressive for us," Jazz coach Tyrone Corbin said. "He didn't want to press. He thought he took a few bad ones in last game. So he was just kind of waiting for the game to come to him. I thought he gave us some good minutes there. We need him to score for us though."
Utah's rookie point guard Trey Burke played in his second game since returning from a broken right index finger in the preseason. He came off the bench again, but started the second half in place of John Lucas III, perhaps a precursor of Burke taking over the starting job. Burke finished with five points, three assists and five rebounds in 19 minutes. Forward Jeremy Evans had 14 points on 7-of-7 shooting in 16 minutes.
