The Buffalo Bills are riding high with a 3-0 start to the 2025 season, but head coach Sean McDermott is far from satisfied. Despite a recent 31-21 victory over the Miami Dolphins, the Bills’ defense, particularly the pass rush led by former first-round draft pick Greg Rousseau, has been under scrutiny. With a hefty four-year, $80 million contract extension signed this past offseason, Rousseau’s lackluster performance through the first three weeks has raised eyebrows, prompting McDermott to issue a stern call to action for the 6-foot-6 defensive end and the entire defensive unit.
A Slow Start for a Big Investment
Greg Rousseau, selected in the first round of the 2021 NFL Draft, has been a cornerstone of Buffalo’s defensive line. His 2024 season, which saw him rack up 8.0 sacks, three forced fumbles, and a career-high 24 quarterback hits, set high expectations for 2025. However, through 100 defensive snaps in the first three games, Rousseau has managed just one quarterback hit, a far cry from the game-wrecking presence the Bills expected when they locked him into an $80 million deal.
Meanwhile, veteran addition Joey Bosa has been stealing the spotlight. “I think Joey’s off to a really good start, creating some disruption back there,” McDermott said after the Dolphins game. Bosa’s ability to pressure opposing quarterbacks has highlighted the gap between his production and Rousseau’s early-season struggles. McDermott didn’t mince words when addressing Rousseau’s performance: “Greg has had some good reps, and then there’s some other things that he would tell you he wants to do better in the first three games. Going forward, we are gonna need that, 100 percent.”
Defensive Scheme Demands More
McDermott’s defensive philosophy hinges on the front four generating pressure without relying heavily on blitzes. “The pass rush is needed. My philosophy is you’ve gotta be able to get there with your front four,” he emphasized. This approach places immense responsibility on players like Rousseau and Bosa to disrupt opposing quarterbacks and create opportunities for the rest of the defense.
Against the Dolphins, the Bills’ pass rush failed to deliver. Miami’s Tua Tagovailoa escaped pressure repeatedly, converting key third downs and keeping drives alive. Buffalo didn’t record a single sack, exposing a critical weakness in McDermott’s scheme when the front four underperforms. For a team with Super Bowl aspirations, this lack of production is a glaring concern.
Rousseau’s Redemption Arc
Despite the slow start, McDermott remains optimistic about Rousseau’s potential to turn things around. “Overall, you’re looking to improve in every area. I know Greg’s committed to that. He’s one of our hardest workers. Very conscientious young man, and a big part of our team,” McDermott said. He even suggested that Rousseau would echo this sentiment, stating, “I betcha if Greg came in here and you asked him the same questions, he’s gonna say I’m working in every area, every aspect of my game.”
Rousseau’s work ethic and commitment aren’t in question, but the clock is ticking for him to translate that effort into on-field results. The Bills face a tough challenge in Week 4 against the Baltimore Ravens, led by the elusive Lamar Jackson. In their previous meeting on September 7, 2025, Jackson’s mobility tested Buffalo’s defensive line, and Rousseau will need to step up to contain the dual-threat quarterback.
A Defense on Notice
McDermott’s comments serve as a wake-up call not only for Rousseau but for the entire Bills defense. With Bosa setting the tone and younger players waiting in the wings, the pressure is on for the unit to elevate its performance. “We need to continue to find players that are gonna help us and add to that mix,” McDermott noted, signaling that no one’s spot is secure if production doesn’t improve.
The Bills’ 3-0 record masks underlying issues that could derail their season if left unaddressed. Rousseau’s $80 million contract comes with expectations of dominance, and McDermott’s public demand for improvement underscores the urgency for the young defensive end to rediscover his 2024 form. As the Bills prepare for a grueling stretch of games, the entire defense is on notice: step up or risk being left behind.
