The Buffalo Bills have faced significant challenges with the indefinite loss of star linebacker Matt Milano due to a torn bicep, necessitating other players to step up. Greg Rousseau shined in the preseason game against the Pittsburgh Steelers, recording 2.5 sacks and earning a high PFF grade of 91.0. Additionally, undrafted rookie linebacker Joe Andreessen impressed by leading the team with 12 tackles and effectively communicating defensive plays, positioning himself as a potential candidate for the final 53-man roster. Rousseau and Andreessen's standout performances have provided a much-needed boost to the Bills' defense, especially with the departures of Leonard Floyd and Von Miller's underwhelming season. Both players have shown promise, with Rousseau aiming to bolster the pass rush and Andreessen making a case for his place in the team. This development is crucial as the Bills aim to overcome formidable opponents like the Kansas City Chiefs.
