Raymond Felton scored 18 points to lead eight Dallas players in double figures and the Mavericks rolled past the Suns 111-95 on Wednesday night.
"It was a tremendous team effort," Dallas coach Rick Carlisle said. "We had eight guys in double figures, which is going to be one of our calling cards because we got to have great balance."
Dirk Nowitzki, in his 17th NBA season, scored nine of his 11 points in the third quarter when the Mavericks built a 27-point lead. Phoenix never got closer than 14 again.
Deron Williams and Dwight Powell scored 12 apiece for the Mavs.
Rookie Devin Booker scored 14 points on 6-of-7 shooting for the Suns, all in the second half. Brandon Knight had 15 points, Jon Leuer 14 and Eric Bledsoe 13 for Phoenix.
Dallas ended the first half with a 13-4 run and started the second with a 12-4 burst for a 66-49 lead on Nowitzki's 22-footer.
"We really got after them and we started to attack the basket," Felton said. "We started making things easy for us."
Phoenix managed a run late. Bledsoe's three-point play, followed by a 13-foot jumper, cut it to 92-78 with 8:06 left. Dallas scored the next seven points with Felton's 3-pointer putting the Mavericks comfortably back on top 99-78 with 6:54 to go. Dallas led by as many as 28 points in the final quarter.
"We stayed in attack mode all night and never let up," Carlisle said, "and that is how we are going to have to play. "
The game was close most of the first half. The Suns' Archie Goodwin made a 3-pointer to tie it 41-41 4:04 before the break. Charlie Villanueva made a 22-footer and a 3-pointer in the surge that put Dallas up 54-45 at halftime.
Coach Jeff Hornacek said the Suns just need to "flush it down the toilet" and go on to the next game.
"I think everybody from top to bottom can take a piece of this loss," said the Suns' Tyson Chandler, who has twice left Dallas in free agency over the past four years.
Williams had been out with a calf injury and didn't play at all until a 15-minute appearance in the team's final preseason game. But he gave the Mavericks a scare when he went down in front of the scorer's table midway through the third quarter. He was helped to his feet and limped off. But the Mavericks pronounced it only a sore knee and Williams was back on the court before the quarter ended.
Booker, barely 19 years old, was the designated sharpshooter off the bench for Kentucky last season, and he made the most of his time on the court in his NBA opener.
His first basket as a pro was a 15-foot jumper with 2:50 left in the third quarter. He ended the quarter with his first NBA 3-pointer.
Hornacek appreciated Booker's aggressive offense, but the youngster has a lot to learn about NBA defense.
"I think he got back-doored on one and that's when a veteran says, 'I got a rookie and I'm going to pick on him,'" Hornacek said. "That's how you learn. Overall, for the first game, I thought he played pretty well."
