This isn’t Joe Lombardi’s first rodeo with Broncos head coach Sean Payton. Far from it.

The Broncos’ offensive coordinator spent 10 seasons as a quarterbacks coach and two as an offensive assistant under the Super Bowl-winning coach in New Orleans. The countless hours in meeting rooms and on the sidelines means Lombardi is well-versed in Payton’s fiery attitude, unwavering self-assuredness and extreme attention to detail.

In Denver, Lombardi is among seven coaches on the staff with a previous relationship with Payton.

Payton’s reasoning behind adding some New Orleans flavor to his Broncos’ staff was simple: They know what he wants.

And for Payton to be competitive first season in Denver, he needed coaches to deliver his expectations to the players while he’s busy with other obligations as he attempts a franchise turnaround.

“When we have to make a decision, you have a good idea for what (Payton) wants to do,” Lombardi told The Post. “You are not always right, but you try to be.”

Lombardi didn’t hesitate when Payton asked him to join his staff. Payton told Lombardi, who spent the past two seasons as the Los Angeles Chargers’ offensive coordinator, that he had a vacant spot on his staff. Lombardi responded by saying he would love to come. Simple as that.

Lombardi had two stints with the Saints. He was the team’s offensive assistant from 2007-08 before being promoted to quarterbacks coach, working closely with future Hall of Fame QB Drew Brees from 2009-13. Lombardi became the offensive coordinator for the Detroit Lions in 2014 but was fired along with several other coaches after a 1-6 start in 2015.

He returned to New Orleans as the quarterbacks coach for five seasons, then left again to orchestrate the Chargers’ offense led by quarterback Justin Herbert.

“When you are away from (Payton), you begin to appreciate things he does,” Lombardi said. “He’s got a good combination of being very demanding (without) making the work day miserable.”

In Lombardi’s third go-around with Payton, he has a clear understanding of his likes and dislikes. Payton leaves no stones unturned when it comes to creating a game plan. He is thorough and wants an answer for every problem a defense can present on Sundays.

However, his preparation comes at a price — which includes Lombardi’s sleep schedule. There are days when he and the rest of the coaches don’t go to bed until midnight, and there are other days when they are awake until 3 a.m.

“Things change, and I give (Lombardi) a hard time,” Payton said. “(When) the whole group gets together, I’m like, ‘What took place?’ They’ll tell me (what), and then I agree to two-thirds of it and get rid of the other third. That’s pretty much how those meetings are going.”

Zach Strief, now the Broncos’ offensive line coach, has seen the Payton experience from the perspective of both a player and coach. He played offensive tackle for the Saints from 2006 to ’17, starting in 94 games and winning a Super Bowl in 2010. Payton’s first training camp in New Orleans was brutal, Strief recalled, saying the then first-year head coach was relentless in trying to establish a culture.

He worked nonstop to create a plan that put players in the best position to succeed, staying at the Saints facility as long as possible to get everything right.

“There’s not a lot of people in the world that can push themselves when no one else is pushing them,” Strief told The Post.

Payton is a teacher at heart. Part of what allowed him to tap into his players’ full potential with the Saints was his ability to educate them on why exactly he was asking them to do certain things in his schemes.

Even as a coach, Strief continues to learn under Payton, who has no problem coming into his office and telling him what he can do better with the offensive line.

“Whether you are a coach or in the communications department, he wants to teach,” Strief said. “He wants the people around him to achieve. Sometimes that comes across a bit rough, but the more you are around him, you appreciate the honesty.”

Strief knows what Payton expects in the break of a huddle and the tempo at the line of scrimmage. He has never been in any other system. All he knows is the Payton way.

Denver’s offensive line will be essential to executing its run-heavy offense. And Strief’s prior knowledge has made it easy for the offensive linemen to get up to speed.

“Coach (Strief) knows what (to) expect in games against certain looks,” Broncos center Lloyd Cushenberry said. “He knows what type of runs (Payton) likes to hang his hat on. (He’s) a good teacher and storyteller.”

Only time will tell if Payton’s decision to bring his former coaches to Denver will be beneficial. At the very least, the Broncos were able to get off to a running start.

“(Everyone) is flowing together,” quarterback Russell Wilson said. “Our meetings are super efficient and we get a lot done.”
