Greg Rousseau
Greg Rousseau has become one of the best run-defenders, not just on the Bills but in the league. He quietly goes about his business, and you rarely hear about it. Against the Steelers, he recorded a sack, four total tackles, a tackle for a loss, and a quarterback hit. According to Pro Football Focus, he earned a run-defense grade of 71.6.
If Rousseau can start adding sacks to his stat line more often, he'll quickly become one of the best defensive linemen on this team. Rousseau's sack of Mason Rudolph was his first career postseason sack. Let's hope he can build on that and get after Patrick Mahomes and the Chiefs in this weekend's divisional-round battle.
