The Buffalo Bills boast one of the NFL’s strongest secondary groupings. The team struggled against the pass in 2017, which was the first year head coach Sean McDermott and defensive coordinator Leslie Frazier arrived. Since that initial season, they have steadily improved as the team’s “brain trust”—which includes general manager Brandon Beane—has had time to add players to the system.
In 2017, Buffalo was ranked No. 20 in total passing yards against. In 2018, they were No. 1, and this year, they were No. 4 overall. As players have become more comfortable in the system, the team has thrived while defending the pass.
