SALT LAKE CITY — The NBA’s most disappointing team just extended the league’s longest losing streak. And the latest loss was more of a destruction than a defeat.

The Nets dug a hole right from the start, jumped in and buried themselves. Playing without James Harden, they were thrashed 125-102 by the Jazz before a sellout crowd of 18,306 at Vivint Arena on Friday night.

The Nets have dropped seven straight, their longest skid since also losing seven in a row from Dec. 26, 2019 through Jan. 7, 2020. No team has ever lost that many in a row and won the NBA title, according to StateMuse. But right now, the Nets need to worry more about just winning a game before they contemplate a championship — and in the battle of wills Friday, they were broken.

“We had a few chances and some of our focus level diminished as they started making shots,” Kyrie Irving said. “We came to the bench, we had some good talks about adjustments we wanted to make, but it was just a battle of will and they took over the game.”

The Nets are 2-8 since Kevin Durant sprained his left MCL, but he wasn’t the only one missing Friday. Harden was held out because of a tight left hamstring, and Nic Claxton left the game due to a hamstring injury of his own.

Irving had 15 points and six assists, but shot 6-for-20 and finished a minus-29. Patty Mills was a minus-27. Starters Claxton, Kessler Edwards and James Johnson combined for a grand total of two points on 1-for-14 shooting from the floor.

That’s the kind of evening it was for the Nets, for whom rookie Cam Thomas’ career-high 30 was about the only bright spot.

“This is one of the worst games I’ve seen all year. This is bad,” one Eastern Conference scout told The Post. “But there’s not much out there.”

The Nets missed their first seven shots, before Johnson broke through drought. By that point the Jazz — playing without Rudy Gobert (calf) and Joe Ingles (ACL) — had run off to a 10-0 lead.

The Nets trailed 68-47 after a first half in which they conceded 59.5 percent shooting by Utah and hit just 33.9 percent themselves.

“We want to be able to impact the basketball on the defensive end so we’re not taking the ball out of the rim every single time,” Irving said. “That’s a demoralizing way to play basketball.”

It just got worse from there.

Donovan Mitchell — who finished with 27 points after missing the past eight games with a concussion — found Eric Paschall for a 3-pointer and 103-69 lead with 35.6 seconds left in the third quarter. Then Mitchell drove for a layup of his own and a 105-71 cushion just 28 seconds later.

The Jazz shot 61.3 percent from the floor — including 54.8 percent from 3-point range — through three quarters, sending the Nets into the fourth trailing 105-73.

“They couldn’t miss at first, so it’s pretty demoralizing when you got to take the ball out of the hoop every time because every single shot they put up in the first five, six minutes [went in],” Thomas said. “They shot like 50-something percent from the 3-point line. It was ridiculous, some crazy stat like that.”

Next up is a game Sunday at Denver, with the Nets trying to avoid an eight-game skid that would be their longest since Nov. 21-Dec. 5, 2018. That losing streak was followed by a seven-game winning streak. These Nets can only hope.

“Tough, tough game. I felt for the guys,” coach Steve Nash said. “I told them I was proud of them just staying together. It’s not easy to take a beating like that and to keep playing hard to the final whistle. We tried to play the right way.”
