Kidd had 20 points and nine assists, hitting 5 of 8 from 3-point range, and the Mavericks recovered from a lethargic start to match the NBA's longest winning streak this season with their 13th straight victory, 96-87 over the New Jersey Nets on Wednesday night.
Butler and Beaubois each added 16 points and Marion had 14 points and 13 rebounds, helping the Mavericks equal Cleveland's winning streak from Jan. 10-Feb. 11.
Nowitzki, who's had 16 games this season with 30 or more points and two with 40-plus, went 3 for 16 from the field and finished with 12 points.
"Dirk didn't play that well, but he's not always going to have 20 or 30 points," Kidd said. "So everybody stepped up. When I get the ball, I know what to do with it."
New Jersey led by as many as 18 in the first half before the Mavericks got untracked to match the third-best winning streak in franchise history, even while Nowitzki was falling 13.3 points under his season average.
"My jump shot was all over the place," Nowitzki said. "But the guys were great. We really wanted this game."
Mavericks coach Rick Carlisle said Nowitzki could be excused for occasionally falling short of his All-Star standards.
"He had an atypical night," Carlisle said. "You're not going to play like an MVP every night. He's earned the right to have an off night."
The Mavericks carried a 70-62 advantage in the fourth quarter, but the Nets pushed back with 11 unanswered points, including six from ex-Maverick Kris Humphries, to pull within 81-80 with 7:40 remaining.
Butler scored eight of Dallas' next 11 points, including a 20-footer with 1:45 left to extend Dallas' lead to 92-87.
"They're a good team and they're going to make a run," Harris said. "They came out and put their foot on the gas. But I'm proud of the way the guys responded. We got it to one, but we couldn't get enough stops to overturn it."
The Nets charged to a 17-3 start, getting seven points from Harris and connecting on seven consecutive field goal attempts.
New Jersey shot 67 percent, converting 14 of 21 from the floor in the first quarter, to build a 33-19 advantage.
The Nets went on to a 41-23 second-quarter lead before the Mavericks finished with a 16-6 run over the final 7:36 of the quarter to cut New Jersey's edge to 47-39 at the break.
Dallas opened the third quarter with a 24-9 spurt that included a pair of 3-pointers from Kidd to grab a 63-56 lead.
"Our defensive disposition was stronger," Carlisle said. "We were more physical. We were more alert."
The Mavericks welcomed back centers Brendan Haywood and Erick Dampier from injury absences. Haywood started after sitting out the two previous games with lower back tightness and had 11 points and 10 rebounds.
Dampier, who missed the previous 12 games with a dislocated right middle finger, had one point in five minutes.
