Buffalo Bills position preview: Who will emerge as the closer opposite Greg Rousseau?
The Bills need more from Rousseau, particularly in key situations when coach Sean McDermott needs his defensive line to get to quarterbacks like Patrick Mahomes and Lamar Jackson.
Editor’s note: This is the second story in a series previewing the Bills’ position groups as training camp looms. Today is edge rushers.

Over the past three seasons, Bills defensive end Greg Rousseau has collected 21 of his 25 career sacks.

Shortly after the Buffalo Bills’ loss to the Kansas City Chiefs in the AFC championship game, general manager Brandon Beane resumed negotiations with the agent for arguably his best defensive player.
The talks ended in March with Greg Rousseau signing a four-year contract extension that tied the talented edge rusher to the Bills through 2029.
The $49 million guaranteed to Rousseau ranks eighth in the NFL at his position, trailing Myles Garrett, Nick Bosa, T.J. Watt, Josh Hines-Allen, Brian Burns, Maxx Crosby and Danielle Hunter.
Rousseau’s $20 million average salary ranks 12th, a potential bargain for a 25-year-old athlete at a premium position with 10 sacks between the regular season and playoffs in 2024. The gradual improvement Rousseau has shown across the past four years, beginning as a rookie first-round pick in 2020, convinced Beane that the best is yet to come for their top defensive lineman.
Rousseau set several career highs in 2024, including quarterback hits (24), tackles for loss (16), solo tackles (36) and forced fumbles (three). The 20 quick pressures – three seconds or less – Rousseau created were tied for seventh-most by an NFL defensive lineman, only one behind the Chiefs’ Chris Jones.
The Bills revamped their defensive line this offseason to try to create more pressure and improve against the run. If others can make more plays, including fellow edge rusher A.J. Epenesa, who’s entering the final season of his contract, then offenses won’t be able to run away from Rousseau or use multiple blockers to try to limit his impact.

Rousseau needs to be more consistent and Bills coach Sean McDermott wants to see another level of physicality from him throughout the season. Someone as big (6-foot-7, 253 pounds) and athletic as Rousseau could be among the NFL’s elite edge rushers. He had some remarkable games last season, like Week 1 when he had six tackles for loss or Week 7 with his six quarterback hits, the highest single-game total by any player over the past two seasons.
But the Bills need more from Rousseau, particularly in key situations when McDermott needs his defensive line to get to quarterbacks like the Chiefs’ Patrick Mahomes and the Baltimore Ravens’ Lamar Jackson.
