Encouraging notes have circulated ahead of the 2026 season, particularly around the impact of the offseason addition of Bradley Chubb. Chubb, who signed a three-year, $43.5 million deal, is expected to serve as the Bills’ top pass rusher. His presence could create more favorable matchups for Rousseau, potentially unlocking higher sacks totals and more consistent pressure off the edge. Rousseau’s development will be crucial for new defensive coordinator Jim Leonhard as he seeks to elevate a unit that has shown flashes but needs more game-changing plays.
Rousseau notably elevated his play during the latter part of the 2025 season. In the final five games, he accumulated 17 tackles, three tackles for loss, four sacks, and 12 quarterback hits, signaling that he can rise to the occasion when given the opportunity and refinement of technique. Analysts have continued to recognize his potential: Pro Football Focus ranked him as the No. 64 player in its top 101 list for the previous season, noting an 80.0+ overall grade in multiple seasons and highlighting his strong run defense (PFF run-defense grade of 85.1). In addition, Rousseau recorded 63 quarterback pressures as a pass rusher, underscoring his effectiveness as a disruptor.
The expectation is that Rousseau can carry forward the momentum into the upcoming campaign. The addition of Chubb could be a catalyst not only for Chubb’s own production but also for Rousseau’s development, potentially positioning Rousseau as the Bills’ primary edge threat and elevating the entire pass rush. If Rousseau makes a leap in his sixth NFL season, he could become a true game-changer for a defense that has shown promise but is seeking a higher impact level.
Bradley Chubb has expressed a focused mindset heading into his new role with the Bills, emphasizing a championship-oriented drive. At 29 years old, his experience and high-level production—evidenced by eight-and-a-half sacks in 2025 with the Dolphins—bring a veteran presence to the defense. His leadership is expected to extend beyond on-field production, supporting Rousseau in the growth process as Buffalo aims to maximize their edge group.
Overall, the Bills’ defensive outlook hinges on Rousseau’s continued improvement and the synergistic impact of Chubb’s presence on the defense. If Rousseau delivers a stronger year and benefits from Chubb drawing attention from opposing blockers, Buffalo could see a more formidable pass rush and a more disruptive defense across the board. The combination of both players’ abilities, along with the scheme under the new coordinator, has the potential to translate into more frequent pressure, more quarterback disruptions, and a higher level of overall defensive performance in 2026.
