NFL’s longest-tenured head coaches after Sean McDermott, Mike Tomlin, and John Harbaugh out

Mike Tomlin and John Harbaugh were the two longest-tenured coaches in the NFL this season. Shortly after them in fourth was Sean McDermott. Now they’re all out after the Baltimore Ravens, Pittsburgh Steelers, and Buffalo Bills all decided to move in a different direction following another disappointing end to their seasons.

Only one NFL head coach was hired before 2017.

Let’s take a closer look at the list of longest-tenured NFL head coaches and some takeaways.

More than 75% of NFL head coaches were hired since 2021

Looking at the list before of the longest-tenured NFL head coaches, you’ll see only seven were hired before 2021. More than three-quarters of the coaches have been upended since COVID, and some teams more than once.

More than 25% of the NFL will have a new coach in 2026 — again

At least 10 of the 32 teams will have a new man on the sideline for the 2026 season opener. On average, the modern NFL turns over seven to eight coaches per hiring cycle. It was seven in 2025, but in 2024 and 2023 it was eight. In 2022 it was nine. Ten is the NFL offseason record and happened a few times before.

Super Bowl wins is a key metric for head coach longevity, but they don’t guarantee it

Obviously in the NFL, the Lombardi trophy is the ultimate goal. Of the coaches that have been around for more than six years, only Kyle Shanahan doesn’t have a Super Bowl victory.

There is turnover even with Super Bowl winners. Only three coaches have won Super Bowls with their current teams; Andy Reid, Sean McVay, and Nick Sirriani. Reid is the only active coach with multiple Super Bowls with his current team.

In the last handful of years, Bill Belichick was fired by the Patriots, Doug Pederson was fired by the Eagles, Pete Carroll was fired by the Seahawks, John Harbaugh was fired by the Ravens, and Mike McCarthy was fired by the Packers despite winning the big one for the franchise. Now Mike Tomlin is out, too.
