The Nets had their worst defensive outing against the league’s best offense.
Brooklyn got shredded 148-111 by Boston before a sellout crowd of 19,156 at TD Garden that relished in a lights-out shooting performance.
It was the most points the Nets had allowed all season.
So was the 66.7 percent shooting they conceded.
So were the misprint-like 64.7 percent from deep, Boston hitting 22-of-34 from 3-point range.
The Nets watched Jaylen Brown put up 28 points, nine assists and seven rebounds.
And watched was the operative word, as he sailed through the lane untouched.
Brooklyn trailed just 82-76 in the third quarter, and got outscored 66-35 the rest of the way in essentially a quarter.
Michael Porter Jr. had 18 points, and rookie Danny Wolf dropped 16 off the bench.
But they got outrebounded 39-25, and never put up any defensive resistance all night.
The Nets (15-43) have dropped seven straight, the second-worst skid in the league.
Brooklyn is still third in the lottery standings and rising up the ranks.
The Nets are just two games behind Sacramento — one in the win column — and a ½ game behind second-place Indiana.
The Celtics have won 10 of their last dozen games and risen to second in the Eastern Conference despite star Jayson Tatum having been out with a torn Achilles and still waiting to make his season debut.
The thought of dropping him into this team should scare the rest of the East.
Boston put on an offensive clinic. Nikola Vucevic had 28 points and 11 rebounds.
Brooklyn led only briefly, up 11-10 after Nolan Traore (seven assists) found Nic Claxton.
But the Nets coughed up a 16-4 run and never led again.
Down 79-65 early in the third quarter, they quickly reeled off eight unanswered in just a minute-and-a-half, Traore’s short jumper pulling them within six.
It was still 82-76 after a Noah Clowney 3-pointer but they watched Boston rip off a dozen straight.
Brown found Sam Hauser to make it 94-76, and the rout was on.
The deficit swelled to 41 in the fourth quarter.
Former Celtic Josh Minott — who’d arrived at the trade deadline and finally made his Brooklyn debut in the Thursday loss — had some promising moments in his return to Boston.
He had some nice passes that his new teammates couldn’t finish, and threw down a fast break posterization of Hugo Gonzalez off a Terance Mann feed.
The Nets inked Grant Nelson to a 10-day deal, giving them six rookies.
The big man made his NBA debut with 9:41 to play, and scored his first points on a dunk with 6:35 left.
“It’s just really a dream come true. So I’m just going to do what I can, continue to keep working and hopefully do whatever I can to help this team win some games,” Nelson told YES Network.
“Obviously my body getting healthy, I missed a lot of the season at the beginning because of my knee. So, they’re doing everything they could to continue to get me on the court. And then just giving me an opportunity like this.”
