Sean Payton broke the coach’s code by ripping a fellow coach, according to the man the new Broncos head man took aim at.

New Jets offensive coordinator Nathaniel Hackett responded Tuesday to Payton’s scathing comments from last week.

“I’ve been involved in this business my whole life — 43 years. As a coach, as a coach’s kid, we live in a glass house. We know that,” said Hackett, who didn’t even wait for questions, starting his press conference with a statement on the matter instead. “There’s a code and there’s a way things are done in that house. This past week, it’s frustrating and it sucks. But we’re all susceptible to it. There are things you do, mistakes you make and it costs you time on the field, it costs you your job, all those things, and I own that stuff. I got no excuses.”

“It’s unfortunate that had to happen, the comments that were made. But, hey, they did [happen]. I was probably more surprised they happened now. I was definitely expecting them in Week 5 [when the Jets face the Broncos]. Almost thankful we got that out of the way, understand the way certain people feel and think.”

In a story in USA Today last week, Payton went after Hackett’s 15-game stint as the Broncos head coach, calling it “one of the worst coaching jobs in the history of the NFL.”

Denver was 4-11 at the time of his dismissal, near the end of by far the worst season of quarterback Russell Wilson’s career. Payton also singled out the Jets as the latest NFL team “trying to win the offseason,” suggesting they are attempting to take a shortcut.

Hackett said Payton has not reached out to apologize, which Payton had said he planned to do. Hackett isn’t expecting to speak to him.

“I’ve never met the guy,” he said.

Aaron Rodgers, extremely close to Hackett, went on the offensive on Sunday, calling Payton “insecure.”

Hackett was Rodgers’ offensive coordinator with the Packers from 2019-21, during which the legendary signal-caller won two MVP awards.

“I think it was way out of line, inappropriate, and I think he needs to keep my coaches’ names out of his mouth,” Rodgers said on NFL+.

Offensive tackle Billy Turner, who played for Hackett with the Packers from 2019-21 and again with the Broncos last year, wrote in an Instagram story that Payton must not have liked what he had seen so far from the Broncos, calling him a “f–king bum.”

Jets coach Robert Saleh was more diplomatic.

“I kind of live by the saying, ‘If you ain’t got no haters, you ain’t popping,’ ” Saleh said. “So hate away. Obviously, we’re doing something right if you’ve got to talk about us when we don’t play you until [Week 5].”

Payton apologized for the remarks, saying he was still thinking like an analyst.

He spent last year working for Fox Sports after 15 years coaching the Saints with a one-year suspension mixed in for his role in the Bountygate scandal.

On Wednesday, Hackett said he wasn’t surprised to be a target.

“You knew he was going to handle it that way at some point,” Hackett said. “That’s how it was going all last year.”

Hackett said he’s received incredible support from everyone in the Jets organization, and Payton’s attack has brought the team closer together.

Criticism isn’t new to him.

He saw how much heat his father, Paul, took at times when he served as the Jets’ offensive coordinator under Herm Edwards from 2001-04.

“All the time,” Hackett recalled with a laugh. He added: “Growing up in this business, you understand you’re going to get it from all areas.”

The back-and-forth will be the leading storyline to the game against the Broncos on Oct. 8 in Denver, a matchup that now holds extra intrigue.

But Hackett wouldn’t say it has extra meaning to him now.

“It’s just another game,” he said.
