Michael Zimmer (born June 5, 1956) is an American football coach. He began his NFL career as a defensive assistant with the Dallas Cowboys in 1994, where he helped the team win Super Bowl XXX in January 1996.
After positions as defensive coordinator for the Atlanta Falcons (2007) and Cincinnati Bengals (2008âÂÂ2013), and head coach of the Minnesota Vikings (2014âÂÂ2021), Zimmer returned to Dallas in 2024 as the team's defensive coordinator. He has earned a reputation for developing top-ranked defenses and fostering strong team performance.
In high school, Zimmer was a successful multi-sport athlete who earned all-conference honors in football (1972âÂÂ73), baseball, and wrestling at Lockport Township High School in Lockport, Illinois. He enrolled at Illinois State University, majoring in physical education. He played quarterback in 1974, but he redshirted the following year and moved to linebacker in 1976 after breaking his thumb. A neck injury prematurely ended his playing career that same year. His college teammates were positively influenced by his constantly "up" attitude, especially during hot August pre-season double workouts. He backed up quarterback Bob Lopez in 1974, who later went on to set many of Illinois State's passing records.
Zimmer's first coaching job was as a part-time defensive assistant at the University of Missouri from 1979 to 1980. He then coached at Weber State College from 1981 to 1988, serving as the inside linebackers coach from 1981 to 1984, the defensive backs coach from 1985 to 1988, and the defensive coordinator from 1983 to 1988. From 1989 to 1993, Zimmer served as the defensive coordinator and defensive backs coach for the Washington State Cougars. In 1993, the Cougars defense ranked eighth in the nation in total defense and second in rushing defense.
He joined the Dallas Cowboys in 1994 as an assistant coach of the nickel defense under Barry Switzer. He was promoted to defensive backs coach in 1995 and served in that capacity before being promoted to defensive coordinator in 2000. The 2003 Dallas Cowboys' defense gave up the fewest yards in the NFL while running an aggressive, speedy 4âÂÂ3 defense. Despite the Cowboys' problems over the years, Zimmer survived several coaching changes (Switzer, Chan Gailey, Dave Campo, Bill Parcells) and was rumored to have been a candidate for the head coaching job at the University of Nebraska (circa 2003). In 2005, he implemented the 3âÂÂ4 defense favored by head coach Bill Parcells, although Zimmer had no prior experience with it.
When Bobby Petrino was hired to coach the Atlanta Falcons early in 2007, Mike Zimmer agreed to become the new defensive coordinator in Atlanta. Zimmer coached in Atlanta for only one season after Petrino left the Falcons for the University of Arkansas after 13 games. Zimmer has been very outspoken against Petrino after Petrino's unexpected departure from Atlanta in 2007.
Zimmer was named the defensive coordinator for the Cincinnati Bengals on January 15, 2008. In 2009, Zimmer earned NFL Assistant Coach of the Year honors from Pro Football Weekly/Pro Football Writers and from CBSSports.com, after guiding the Bengals to the fourth-ranked defense in the league. In 2011, the Bengals defense finished with in total yards and in points allowed.
In 2012, the Bengals defense finished sixth in total yards and eighth in points allowed, prompting the Cleveland Browns to interview Zimmer for their head-coaching vacancy. The Browns eventually hired former offensive coordinator Rob Chudzinski on January 11, 2013.
On January 15, 2014, Zimmer earned his first head-coaching position when the Minnesota Vikings hired him to replace Leslie Frazier. Zimmer was the ninth head coach in Vikings history.
Zimmer earned his first win as the Vikings' head coach on September 7, 2014, against the St. Louis Rams, with a score of 34âÂÂ6. He ended his first year with a 7âÂÂ9 record, an improvement over the team's 2013 record of 5âÂÂ10âÂÂ1, and the best record for a first-year head coach in the Minnesota Vikings franchise since Dennis Green in 1992.
In 2015, Zimmer improved on his 2014 record by ending the season with a record of 11âÂÂ5 and winning the NFC North, ending Green Bay's streak of four consecutive division titles and giving the Vikings their first since 2009. At TCF Bank Stadium, the Vikings lost the wild-card playoff round to the Seattle Seahawks 10âÂÂ9 while playing in subzero temperatures and the third-coldest game in NFL history.
On July 28, 2016, Zimmer signed a contract extension with the Vikings.
Zimmer suffered a detached retina during the October 31, 2016, Monday Night Football game against the Chicago Bears. On a windy night at Soldier Field, the edge of Zimmer's playcard, which was laminated, blew into his eye. Zimmer underwent emergency eye surgery on November 30, 2016, forcing him to miss the Vikings' Thursday Night Football game against the Dallas Cowboys. Special teams coach Mike Priefer served as interim coach for the game. Zimmer finished the 2016 NFL season with a record of 8âÂÂ8 and the Vikings failed to make the playoffs.
In 2017, Zimmer led the Vikings to one of the greatest seasons in franchise history. The Vikings finished 13âÂÂ3, tallying the seventh-best regular season record in franchise history in terms of win percentage, and the second-best 16-game regular season record in franchise history. Only the 1998 Vikings hold a better record, at 15âÂÂ1. In the playoffs, the 2017 Vikings beat the New Orleans Saints in the with a last-second touchdown pass from Case Keenum to Stefon Diggs, which became known as the "Minneapolis Miracle". They then lost the NFC Championship game to the eventual Super Bowl champion Philadelphia Eagles.
On September 9, 2018, Zimmer became the fourth head coach in Minnesota Vikings history to get 40 wins. The Vikings finished the 2018 season with a record of 8âÂÂ7âÂÂ1 and failed to make the playoffs after losing a "win-and-in" game to the Chicago Bears during the final week of the season.
On February 27, 2019, the Vikings exercised their option to keep Zimmer through 2020. On October 24, 2019, Zimmer became just the third coach to surpass 52 franchise wins, surpassing Jerry Burns; trailing only Dennis Green (97) and longtime coach Bud Grant (158).
The Vikings were able to return to the postseason in 2019. After upsetting the New Orleans Saints in the wild-card round, winning 26âÂÂ20 in overtime, Minnesota fell to the top-seeded San Francisco 49ers in the divisional round, 27âÂÂ10.
In late July 2020, Zimmer signed a three-year contract extension.
Hampered by injuries and opt-outs by many starting defensive players (including defensive end Danielle Hunter missing the entire 2020 season with a neck injury and new free-agent acquisition Michael Pierce opting out of the season due to COVID-19), the Vikings suffered a 'down year' with a 7âÂÂ9 record in 2020, missing the playoffs and finishing third in the NFC North. This was Zimmer's first losing season as a head coach since 2014.
The 2021 season produced similar results to the 2020 campaign finishing with an 8âÂÂ9 record. On January 10, 2022, Zimmer was fired as head coach of the Minnesota Vikings, ending his eight-year tenure with the team. Zimmer finished his tenure with the Vikings with a record, which includes a playoff record.
On February 12, 2024, Zimmer was hired by the Dallas Cowboys to be their defensive coordinator for a second time, now under head coach Mike McCarthy, to replace Dan Quinn, who left to become head coach for the Washington Commanders. On January 26, 2025, it was announced that Zimmer would not return to Dallas in 2025, and would likely retire.
Zimmer is the son of former NFL player and coach, Bill Zimmer, who died on August 12, 2015, at age 84. His wife, Vikki, died unexpectedly at their Ohio home on October 8, 2009. Three days later, Zimmer was awarded the game ball by Bengals head coach Marvin Lewis after the team's 1714 victory over the Baltimore Ravens.
Zimmer has three children: Adam, Corri, and Marki. Adam was a coach and served as an assistant linebackers coach with the New Orleans Saints during their Super Bowl winning season. Adam Zimmer died unexpectedly on October 31, 2022.
