Brooklyn put on a dominant display, and didn’t need Kevin Durant to do it.

In a season filled with brilliant offensive performances, this may have been the best, as the Nets cruised to a 136-125 laugher at Golden 1 Center.

Kyrie Irving — playing more off the ball lately — was freed up to pour in a season-high 40 points. James Harden had another triple-double with 29 points, 14 assists and 13 rebounds. And he perfectly orchestrated an offense that shot 57.3 percent and hit a team-record 27-of-47 from deep, just two shy of the NBA record.

But in a game that saw the Nets (17-12) lead by as much as 28, it was earning a third straight win with some timely defense that may have been most auspicious. They got 11 consecutive stops and held Sacramento scoreless for five straight minutes in a 20-0 third-quarter run to blow it open.

“Yes, because it’s a total team effort. Obviously, we’d love to have Kevin back for more than one game,” Harden said. “Once we can get that full roster, then we can really see what we got and we can really be something special. But until then, defensively its going to have to be our mindset, because offensively, like I keep harping on, we can score with the best of them.”

Irving showed that, shooting 15-of-22 overall and 9-of-11 from deep. He even left Harden in awe at times.

“It’s a movie. It’s like a show. Sometimes, I forget I’m on the court. He makes them look so effortless. It’s one of the reasons why I’m here,” said Harden, taking on more playmaking and freeing Irving to score.

“I just try to get guys in their spots and make sure I’m feeding everybody across the board. Now that I’m getting familiar with Ky more, I know his spots and where he likes the ball and we just let him go and be free and do what he does at a high level because he’s one of the best that this game has ever seen doing that.”

With Durant sidelined by a hamstring injury, the Nets were clinging to an 82-80 lead in the third quarter before reeling off 20 unanswered points.

Harden started it with a feed to Jeff Green for a thunderous dunk, and capped it with a step-back 3-pointer. The Nets hit 8-of-9 shots and held Sacramento to seven straight misses with four turnovers.

“The defensive side, our communication has been a lot better. We’ve been doing the second level, second effort way better, being there for our teammates. That’s what we needed to get over the hump,” Green said. “But that’s only a couple of games. We have to continue the process of getting better at that end because we can be better.”

Which is a scary thought.

By the time the run was done, the Nets led by 22. It stretched to 128-100 on another Green 3 midway through the fourth, and the rest of the evening was a fait accompli as they won their third straight since a humbling loss in Detroit.

“It’s a good sign,” Steve Nash said. “We addressed the performance in Detroit. We saw a response, and they’ve been able to build on it.

“We had a tough stretch here; tomorrow will be three games in four nights and then I think the Lakers will be four in six. It’s a tough stretch, but to get three in a row here is really, really positive and it shows the toughness that we have when we stick together and keep fighting.”

Green and Landry Shamet had 13 points each, while Tyler Johnson and Joe Harris added 10.

Harden said it was performances and games like this that he imagined when he came to Brooklyn.

“This was the vision right here, this game itself,” Harden said. “Obviously, KD was out, but it was next man up. Tyler did an unbelievable job of coming in and playing really good minutes. And from top to bottom, everyone has the same goal and that’s to win.”
