Eddie Yarbrough and Ryan Davis have carved out niche roles in the Bills defense and have performed admirably in those roles over the past few games.
Against the Colts, Yarbrough received a run-defense grade of 82.4 – which places him firmly in PFF's "very good" range – the 14th-best grade among 133 edge-rushers in Week 14.
But it wasn't an isolated performance from the former Wyoming star.
Yarbrough had a 75.5 run-defense grade against the Patriots the week before – which falls in the "average" range – and the 19th-best run-stopping grade (81.5) among 132 edge-rushers in Week 12 during Buffalo's game at Kansas City.
On the season, Yarbrough's run-defense grade is 78.9, the 39th-best score among 108 qualifying edge-defenders.
Meanwhile, despite a pass-rushing grade on the season of 72.6, which places him at the No. 62 spot, Davis has emerged in that area over the past two weeks.
His pass-rushing grades have been "average." He managed seven quarterback pressures (one sack, one hit, five hurries) on just 26 pass-rushing snaps in games against the Patriots and Colts.
In the snow on Sunday, Davis turned 15 pass-rushing snaps into five pressures (one sack, four hurries) which were the most by a player on either team.
On the year, Davis has generated 21 quarterback pressures – the fourth-most on the team – on just 190 pass-rush snaps.
With Shaq Lawson sidelined with injury, the specialties of Yarbrough and Davis will be crucial for Buffalo in its last three games of the regular season.
