Rousseau's Sack Surge: Bills' Star on the Rise

The Buffalo Bills' defense has faced challenges in the early 2026 NFL season, surrendering an average of 26.8 points per game. However, their pass-rushing unit has been a bright spot, with the team tied for sixth in sacks heading into Week 5. Leading this charge is outside linebacker Gregory Rousseau, who currently tops the NFL with six sacks in just four games.

Rousseau's exceptional performance extends beyond sacks; he also leads the league in quarterback pressures (29), tackles for loss (8), and forced fumbles (3). This resurgence is attributed by some to a potential maturation or better fit within the new 3-4 defensive scheme under coordinator Jim Leonhard. His early season success earned him AFC Defensive Player of the Month for September.

Former NFL offensive lineman Terron Armstead has taken notice, stating he always saw breakout potential in Rousseau, affectionately known as "Groot." Armstead believes Rousseau is currently "watching a star (be) born," highlighting his speed, size, strength, and awareness. He anticipates Rousseau, alongside running back James Cook III, will be key "X-factors" for the Bills in their upcoming Monday Night Football matchup against the Los Angeles Rams.
