Despite strong effort and clutch play, costly turnovers and James Harden's dominance sealed the Mavericks' heartbreaking double-overtime defeat.
DALLAS — By the time James Harden hit the free throws that finally pushed the Clippers ahead for good, the deep blue court inside American Airlines Center felt less like a stage and more like a reminder of how far the Mavericks still need to climb. A trophy sat at midcourt before tipoff to commemorate the Mavericks’ first home NBA Cup game, but the significance faded quickly as Dallas suffered a 133-127 double-overtime loss — another night of great effort undone by the same issues that have defined their season.
The Mavericks dropped to 3-10 overall, 0-7 against the Western Conference, and 0-2 in group play. They battled through 58 minutes, forced 16 turnovers, matched the Clippers with 58 points in the paint, pulled down 50 rebounds, and pushed Harden and Los Angeles to their limits. But they also committed 25 turnovers, gave away 23 points directly off those mistakes, and continued a trend that now defines their profile: the Mavericks are 2-8 in clutch situations, the most losses in the NBA under the league’s five-point, five-minute criteria.
“We struggled in a couple possessions,” Kidd said. “Once we got the ball into Cooper’s hands late, he capitalized and scored, but we needed to get into our stuff earlier.”
They are now averaging 17.1 turnovers per game — 28th in the league, ahead of only Utah and Washington — and have posted just a 91.7 offensive rating in clutch minutes, a mark that ranks 25th. Their overall offensive rating sits at 104.4, which ranks 29th.
For a team playing hard, competing late, and receiving big individual performances, the patterns are clear and increasingly costly. Here’s what stood out.
1. Turnovers are becoming the defining problem
Dallas committed 25 turnovers, tying their second-highest mark of the season. Some were the result of aggressiveness; others were the kind of unforced, late-game mistakes that repeatedly flatten momentum. Seven came from D’Angelo Russell. Four came from Cooper Flagg. Three each came from Daniel Gafford and Brandon Williams. Two of the most damaging occurred in the second overtime, when Dallas needed only clean possessions to sustain control.
Jason Kidd didn’t hold back in his assessment, explaining that these moments keep sabotaging otherwise winnable games.
After the loss, Kidd said the team cannot expect consistency until it controls these sequences.
“We have to address it,” Kidd said. “We have to do better if we want to win — being able to get a shot, and then you want to get a quality shot. The turnovers hurt us. In overtime, we had turnovers where we didn’t get a shot.”
Flagg’s perspective echoed the same urgency, and his reflection carried the weight of someone learning how slim the margins are in the NBA.
“Turnovers,” Flagg said. “That’s a big thing. Some late-game stupid turnovers. And then not getting great shots. When we have empty possessions and don’t get shots up, it’s tough to win.”
Dallas is tied for the league lead with 12 turnovers in clutch situations. The recurring theme is unmistakable.
2. James Harden controlled the night, and Dallas struggled to displace him
Harden’s triple-double — 41 points, 14 rebounds, 11 assists, and six made threes — was the first 40-point triple-double in Clippers history. More important than the numbers was the rhythm he imposed. He dictated pace, drew fouls, slowed possessions when necessary, sped them up when it benefited his team, and delivered 10 points in overtime, including the free throws that sealed the game.
Kidd spoke with the perspective of someone who has guarded and coached against Harden for years.
“You have to show your hands, but he’s the best at drawing fouls,” Kidd said. “He understands what he has to do — time and score. It’s not always scoring the ball; it’s getting to the free-throw line, and that leads to scoring. He gets to the shot he wants, and that’s the difference between great players and average players.”
Russell added the player’s view of Harden’s ability to disrupt defensive stability.
“There’s an element of surprise in how he attacks you and manipulates defenders,” Russell said. “You have to stay disciplined.”
Dallas played hard enough defensively to win most games. Harden imposed a different standard.
3. Cooper Flagg played 48 minutes like someone who has been here before
Flagg’s 16 points on 8-of-13 shooting undersell how steady and unfazed he was in the longest game of his young career. He tied the game with a tough floater late in regulation, absorbed defensive attention, and continued to show feel in tight spaces. At 18 years old, he has now scored in double figures in 12 of his first 13 career games.
He is averaging 15.2 points, 6.6 rebounds, and 3.1 assists in 13 appearances — production that puts him in rare company among Mavericks rookies and ranks near the top of this year’s class.
When asked about how he approaches late-game matchups against physical veterans, Flagg pointed to the mental side of his development.
“Just figuring out the spacing, attacking those guys, trying to make a play,” he said.
He later expanded on the execution issues that continue to surface.
“We just have to be tighter — tighter with the ball, tighter with communication, our setup, our spacing,” Flagg said. “It all goes into it.”
The Mavericks rely on him heavily, and he continues to look like someone capable of carrying that responsibility — even as the losses mount.
4. Naji Marshall might be Dallas’ most consistent two-way force right now
With PJ Washington sidelined by a left shoulder strain and Anthony Davis still out, Dallas had to lean heavily on Naji Marshall. He delivered one of his most complete games as a Maverick, scoring 28 points on 8-of-19 shooting with three made threes and nine free throws. He added eight rebounds, defended Harden for long stretches, and logged 47 minutes without dropping energy.
Marshall has now averaged 19.0 points, 6.4 rebounds and 2.8 assists over his last five games — a stretch where he’s been one of the few constants amid rotating injuries and lineup adjustments.
Kidd made a point to emphasize Marshall’s impact on both ends.
“He did a great job on Harden,” Kidd said. “He competed. Offensively he got to the paint, got to his floater, and he knocked down three threes for us. He played a complete game on both ends.”
Russell framed Marshall’s value in terms of winning habits.
“He was scoring for us, and he’s picking up the best player full court,” Russell said. “When you talk about impacting winning, teams want guys like that… he makes my job easier.”
On a night where Dallas’ mistakes cost them, Marshall’s consistency was a reminder of what steadiness looks like.
5. Dereck Lively II’s return steadied the interior — but couldn’t offset the frontcourt deficit
The Mavericks received a boost with Dereck Lively II returning from a nine-game absence. He played 17 minutes, scored four points, grabbed five rebounds, and blocked three shots. His presence alone changed the shape of Dallas’ defense, giving them a vertical anchor they’ve missed.
Lively has now averaged 5.0 points, 5.0 rebounds and 2.3 assists in four games this season. But the reality is simple: Dallas still hasn’t played a single game with Anthony Davis, Daniel Gafford, and Lively all available — and it showed again.
Ivica Zubac dominated with 27 points and 11 rebounds. Harden’s penetration repeatedly forced rotations that pulled Dallas out of structure. Without Davis, Dallas is now 1-7 this season. They are 2-3 when he plays.
Lively’s return helped, but he alone cannot solve the Mavericks’ frontcourt instability or their late-game issues.
