Brian Flores or a Vikings DC successor will not have Mike Pettine around for experienced help in 2026, however. The veteran staffer is retiring, Kevin O’Connell announced Tuesday.
Pettine, 59, has coached in the NFL since 2002. He rose to a head coaching seat in 2014 (with the Browns) and has been a coordinator in a few cities. He had been on O’Connell’s Minnesota staff since 2022, working under Ed Donatell and then Flores as an assistant head coach.
Jumping from the high school level to a Ravens assistant in 2002, Pettine became a defensive coordinator in 2009. The Jets, Bills and Packers employed Pettine as a DC. He started out in that position with the Jets under Rex Ryan. Pettine played a key role in the Jets making back-to-back AFC championship game appearance, as Revis Island formed to bolster Gang Green’s defense-powered operation in Ryan’s early years. Pettine stayed on as New York’s DC for four seasons before moving to Buffalo under Doug Marrone. Following that season, the Browns concluded a slow-moving HC search by naming him their next leader.
Pettine’s first year in Cleveland (2014) brought some unexpected success. Despite Jimmy Haslam overreach leading to a Johnny Manziel first-round selection, Pettine had the Browns — who were without top receiver Josh Gordon for most of the 2014 season — at 7-4. Cleveland-area native Brian Hoyer had quarterbacked the Browns to that point, as Manziel needed extensive development before debuting. Pettine’s defense also ranked ninth that season. But Manziel received the call to start near the end of the year. The bottom fell out for the Browns, who finished 7-9, and Pettine’s 2015 season keyed a descent.
On- and off-field Manziel problems engulfed the Browns in 2015 — before the team cut the megabust. After letting Kyle Shanahan out of his OC contract following a 2014 one-off, Cleveland finished 3-13 in Pettine’s second season. The team used Manziel and free agent signing Josh McCown as their primary QBs, and ownership fired he and GM Ray Farmer. Pettine resurfaced with the Seahawks as a consultant in 2017 and with the Packers as their DC by 2018.
In charge of two Packers defenses that appeared in NFC championship games, Pettine lasted three seasons in Green Bay. Pettine’s 2019 and ’20 Green Bay defenses ranked ninth and 13th, respectively, in scoring, but NFC title game letdowns ensued. Raheem Mostert ran wild on the Packers in the 2019 conference championship round, producing the second-most playoff rushing yards in NFL history, and the Packers gave up 31 points to the Tom Brady-piloted Buccaneers a year later in a home loss.
Although the Pack intercepted three Brady passes in the second half of that game, the team did not renew his contract in 2021. He worked as a Bears assistant under Matt Nagy before trekking to Minnesota. Pettine served as outside linebackers coach with the Vikings, who had two Pro Bowl OLBs (Jonathan Greenard, Andrew Van Ginkel) in 2024, over the past two seasons.
