The sight of his superstar quarterback, Josh Allen, devastated in the visiting locker room in Denver in the moments after the Bills’ devastating AFC divisional round playoff loss to the Broncos last January was an enlightening moment for team owner Terry Pegula.

“I looked around, and the first thing I noticed was our quarterback with his head down, crying,” Pegula said. “I saw the pain in Josh’s face at his presser, and I felt his pain. I know we can do better, and I know we will get better.”

Thus, Pegula fired head coach Sean McDermott, the coach who rescued his sagging franchise, ended the embarrassing 17-year playoff drought in his first season in 2017 and proceeded to lead the Bills into the playoffs in eight of nine seasons, winning five AFC East titles and appearing in two AFC Championship Games. McDermott’s Bills won more games from 2017-25 than every other NFL team except the Kansas City Chiefs.

But while the Chiefs won five AFC titles and three Super Bowls in that span, the Bills won zero and zero.

With Allen turning 30 in May, Pegula felt the time had come to try something different because, as he said, “I felt like we hit the proverbial playoff wall year after year.”

Offensive coordinator Joe Brady was promoted to the big office, and new defensive coordinator Jim Leonhard was hired to make changes to a unit that has repeatedly let the Bills down in January.

It’s a new era in Buffalo, and there’s also a whole lot of pressure on Brady, the youngest head coach in the NFL at 36, as he steps into a situation where he’s walking a tightrope with no safety net.

The Bills, the only team in the NFL to have qualified for the playoffs seven seasons running, remain in win-now mode, and Pegula has made it clear that just making it to the tournament isn’t good enough. Nothing less than a Super Bowl championship, or at the very least, a Super Bowl appearance, is going to cut it with Allen in the prime of his career.

Offense

Brady was the last man standing after nine head coach interviews, and one of the key reasons is that Pegula and president/general manager Brandon Beane wanted the offense to keep rolling as it had with Brady as coordinator.

The Bills tied for fourth in scoring, ranked fourth in total yards and led the NFL in rushing last season. James Cook III ran for an NFL-best 1,621 yards, and his 56.6% success rate was second only to Kyren Williams among backs who topped 1,000 yards. He produced 68 first downs and scored 12 TDs playing behind one of the best run-blocking offensive lines in the NFL. However, the Bills lost left guard David Edwards in free agency, and they don’t have a great alternative in place on the roster.

Even though the Bills’ wide receiver room was underwhelming for a second straight season, Allen improved his completion percentage from 63.6% to 69.3%. That was partially the result of his reliance on easy, quick passes because the WRs had so much trouble getting open in the intermediate areas. Allen also threw 10 picks and was sacked a career-high 40 times, the majority of those because he held the ball too long waiting for someone to get open.

To remedy their weakness at the receiver position, the Bills acquired DJ Moore in a trade with the Chicago Bears and drafted Skyler Bell in the fourth round. There’s optimism that Khalil Shakir can remain an effective slot weapon, that Joshua Palmer can stay healthy and deliver on his 2025 free-agent promise and that Keon Coleman can put two sloppy years behind him and play like a second-round pick. If all that happens, the offense should keep humming.

Defense

After nine years in McDermott’s 4-2-5 base nickel, Leonhard is implementing a 3-4. The transition does raise some concerns because so many of the Bills’ returning players were drafted and developed to play in the old defense. Now, everyone in the front seven has to learn a slightly different position, and the question will be how quickly the Bills can get past the growing pains.
