Bills HC Sean McDermott Points Out 3 Critical Mistakes He Made In Home Loss To Patriots

Orchard Park, NY – In the wake of the Buffalo Bills' first setback of the 2025 NFL season—a narrow 23-20 defeat to the New England Patriots at Highmark Stadium on October 5—head coach Sean McDermott stepped up to shoulder the blame, framing the loss as a critical learning opportunity for his team. The Bills, who entered the game undefeated at 4-0, saw their perfect start snapped by a resilient Patriots squad led by rookie quarterback Drake Maye, who orchestrated a game-winning field goal drive in the final minutes.

McDermott, known for his accountability-driven leadership since taking over in 2017, addressed the media in a post-game press conference, owning up to the team's shortcomings without pointing fingers. "This one starts with me. As the head coach, it's my responsibility to have us prepared and executing at a high level, and we fell short today," McDermott said. "We made too many mistakes—penalties, turnovers, missed assignments—that cost us the game. But that's football; it's about how we respond. We need to grow from this, learn from these errors, and come back stronger. Our guys fought hard, but we have to be better in all phases."

The game was a tale of self-inflicted wounds for Buffalo, with 11 penalties for 90 yards, including costly holding calls and unnecessary roughness flags that extended Patriots drives. Quarterback Josh Allen threw for 285 yards and two touchdowns but was intercepted once in the red zone, while the defense struggled to contain Maye's scrambling ability, allowing 145 rushing yards. Despite a late rally that tied the score at 20-20, the Bills couldn't capitalize on their final possession, punting away their chance after a three-and-out.

McDermott's emphasis on growth echoes his philosophy of building a resilient culture, as he's often highlighted in past seasons. "We've been here before—early losses that test us," he added, referencing the team's bounce-back ability in previous years. "The key is turning this into fuel. We're still in a great position at 4-1, but we can't afford complacency." Players echoed their coach's sentiments, with Allen noting, "Coach always leads by example. We all own this, and we'll fix it."

The loss drops the Bills into a tie for first in the AFC East with the Patriots, who improved to 3-2 under head coach Jerod Mayo. Buffalo now turns its attention to a Week 6 matchup against the Falcons, where McDermott stressed the importance of film review and practice adjustments. "We'll dissect every play, every decision. That's how we improve," he concluded.

As the Bills navigate the rest of the season, McDermott's willingness to take the heat could galvanize the locker room, much like it has in past campaigns that led to playoff runs. Fans and analysts alike are watching to see if this hiccup becomes a turning point for another deep postseason push.
