As the 2026 NFL season approaches, the heat is already rising on several head coaches—and training camp hasn't even started yet. Last season was a whirlwind of change, with longtime leaders like Mike Tomlin (Steelers), John Harbaugh (Ravens), Sean McDermott (Bills), and Kevin Stefanski (Browns) all shown the door after years at the helm.

What did these coaches have in common? A sense that their teams had hit a ceiling. All except Stefanski were steering playoff-caliber squads, and both Tomlin and Harbaugh had brought Super Bowl glory to their cities. But in the NFL, standing still is moving backward. Owners are notoriously impatient, and a championship window only stays open for so long.

Here are the coaches entering 2026 with their futures already under a microscope.

Kyle Shanahan, San Francisco 49ers
There's no denying Shanahan is an elite football mind—but it's fair to wonder if he's squeezed every drop of potential out of this 49ers roster. The situation in San Francisco is starting to echo Andy Reid's final years in Philadelphia, where something just wouldn't click to push the team over the top.

Shanahan was my personal Coach of the Year in 2025, navigating a tidal wave of injuries to keep the 49ers competitive. But if this team gets healthy and still can't make a Super Bowl run, the questions will only grow louder. Shanahan has two NFC Championship appearances and five playoff berths to his name, yet his career win percentage sits at .550. Year after year, his teams are picked to contend—and year after year, they fall just short.

This wouldn't be about poor performance. It would be the painful realization that the status quo has run its course for both sides.

Zac Taylor, Cincinnati Bengals
At some point, this was bound to catch up with him. Taylor is widely regarded as one of the NFL's weakest head coaches, but he meets one critical criterion for Bengals ownership: He's cheap. That's honestly the only reason he's lasted this long in Cincinnati.
