This is what an engaged Nets team can look like. And it’s impressive.

With the Nets’ Big Three playing on a big stage, they stormed to a come-from-behind 124-120 statement win against the league-leading Clippers on Tuesday at Barclays Center.

After getting served a huge helping of humble pie in Sunday’s collapse at last-place Washington, the Nets bounced back against the best team in the NBA.

“We knew they’re in contention for meeting us down the line, so we wanted to come out and make an impression,” Kyrie Irving said in an on-court TV interview, after he poured in a game-high 39.

James Harden backed up the idea of a statement win against a team they could face in the NBA Finals, adding, “Same way, same feeling.”

Despite an empty Barclays Center, this one did have a playoff vibe.

Trailing by a dozen early on and five with under seven minutes left, the Nets seized the momentum. Irving had eight points in a pivotal 13-0 run to take control.

And this time — unlike Sunday in Washington, when they blew an 18-point cushion, and five-point with under 10 seconds to play — they held onto it.

The Nets led 118-108 on a 3 by Kevin Durant (28 points) with 1:55 left. They saw the Clippers score nine unanswered to draw within one on a 3 by Paul George (26 points), but Durant hit two at the stripe with 9.8 seconds to play.

Kawhi Leonard (33 points) hit a pair of free throws, but Harden found Jeff Green for a layup with 5.5 seconds remaining to pad it back to three. Harden then wisely took a foul to prevent a game-tying 3. Nic Batum made just one of two free throws with 2.7 seconds in regulation, and Brooklyn made sure there was no overtime.

“They responded,” said coach Steve Nash, who saw his porous defense hold the NBA’s top team to 45.5 percent shooting. “The team with the best record was in front of them, and they had to put in a good performance. They were really, really competitive; they wanted it and that’s what it’s going to take.”

The Nets — second in the East — usually do respond against the best. They are an NBA-best 9-3 vs. teams .500 or better, having beaten the top two seeds in the West (Clippers, Jazz), and first and third seeds in the East (76ers, Bucks).

“Once we get that down pat, eventually you’re talking about blowing teams out,” said Harden, who had a triple-down with 23 points, 14 assists and 11 boards.

“Every game it means a lot to us,” Irving said. “We’ve just got to come out and show it. [Tuesday] it was easy to go out and do that. After the game, we talked about coming together against teams that may not have the record that shows it, and we’re playing to their level or we’re not playing to exceed the effort that’s needed. We want to make consistent habits of playing the right way every game.

“We just have to take pride in coming out and understanding that every team is going to give us their best shot. We’re one of those teams in the league, but we have to continue to earn that respect.”

Brooklyn fell behind 14-4 to start the game. Leonard’s fadeaway left the Nets in a 20-8 hole less than midway through the first quarter.

The Nets trailed 56-45 on a Marcus Morris 3 late in the half. But they mounted a 19-4 run that spanned intermission, going ahead by four on Durant’s pull-up.

“We finally woke up, though,” Harden said. “They were getting to whatever they wanted.”

The Nets did stumble in giving up a 7-0 run, falling behind 102-97 on George’s and-one with 6:58 to play. But they responded, led by Irving and their maligned defense.

Brooklyn held the Clippers scoreless for three minutes, forcing six straight misses. Meanwhile, the Nets knotted it on an Irving 3 and then went ahead on his Euro step and acrobatic reverse. His transition pull-up 3 pushed the lead to five, and Harden’s step back 3 made it 110-102 with 4:10 left in regulation.

The Nets never trailed again.

“For us that’s the key, is bringing that mentality and concentration to grow every single night,” Nash said. “We’ll be a good team if we do that.”
