Things did not end well between the Minnesota Vikings and Mike Zimmer four years ago, when he was shown the door. The veteran coach has taken several shots at his old franchise. Last year, he was reportedly set to retire, but a comeback is in the works.

The Denver Broncos could be the next stop in his NFL career, where he would reunite with his old coworker Sean Payton. The two experienced skippers crossed paths on the Dallas Cowboys staff from 2003 to 2005. He also knows Broncos GM George Paton from his time in Minnesota.

Broncos insider Mike Klis reported Monday, “Per source, #Broncos visited last week with veteran coach Mike Zimmer about a senior coaching position. Nothing imminent but there is mutual interest. Zimmer has been a football coach since 1979 and started his NFL career in 1994.”

Zimmer was the Cowboys’ defensive coordinator in 2024, but his unit left much to be desired. When the organization parted ways with head coach Mike McCarthy, Zimmer was not retained and decided to call it a career. Looks like that might have only lasted a year.

His previous job in the NFL was with the Vikings, whom he head-coached from 2014 through 2021. When he arrived, he took over a franchise without an identity, and he quickly established a culture — and a defense — that regained national respect for his club.

At his peak, he led the Vikings to the NFC Championship game in 2017 behind an outstanding defense. In his eight seasons, the Vikings ranked 7th in points allowed. Excluding 2020 and 2021, his squad ranked 2nd, trailing only the Patriots.

In his final two seasons in Minnesota, the defense was the clear weakness. Perhaps he failed to make adjustments later in his career, but it’s only fair to note that he worked with subpar defensive personnel in both years and injuries further increased the struggles.

But he didn’t just get fired for his defenses; the culture in the building had reached a point where the usually patient Vikings ownership group wanted to overhaul everything, letting go of both Zimmer and GM Rick Spielman.

Zimmer gave a feisty interview in September 2024, telling the Star Tribune that he hadn’t watched a single Vikings game in the two seasons since his departure.

A couple of storylines about him not getting along with general manager Rick Spielman, going so far that they didn’t even talk in the later stretches of their Vikings’ employment, and the fact that Zimmer refused to address the locker room following his dismissal because his players got him fired. All of that might explain why the team didn’t reach the postseason in his final two years with the organization.

Still, during his time with the Vikings, he oversaw the team with the 10th-best record, 72-56-1, His playoff success was limited to a couple of wins, both over his potential new boss, Sean Payton and his Saints.

At the end of the day, Zimmer is still viewed as a brilliant defensive mind and that’s why the Broncos are interested. They have one of the league’s elite units and want to keep it that way.

Chad Jensen of SI.com commented, “The Broncos fielded one of the NFL’s best defenses in back-to-back seasons, leading the league in sacks over that span. Defensive coordinator Vance Joseph has done an excellent job, and he’ll be returning in 2026 after all the head-coaching vacancies dried up.”

Joseph was viewed as a hot head coaching candidate, but like Brian Flores, hasn’t gotten the desired interest.

“The Broncos lost their defensive-coordinator-in-waiting when Jim Leonhard was hired by the Buffalo Bills last month. Zimmer is getting up there in age, but if he’s hired as a senior assistant, it makes me wonder whether he’ll be the fail-safe in the event that Joseph finally gets a second bite at the head-coaching apple following the 2026 season.”

If the Broncos do add Zimmer in a senior advisory role, it would mark a notable return for one of the most influential defensive minds of the past decade. While his tenure in Minnesota ended on a complicated note, his reputation around the league as a defensive strategist remains intact, which helps explain why a contender with an already strong defense would explore adding his experience to the coaching staff.

Zimmer, 69, might not be done with the NFL after all.
