In 2017, the Buffalo Bills exceeded expectations, posting a 9-7 record and returning to the playoffs for the first time in 17 years before bowing out to the Jacksonville Jaguars in the Wild Card round.
In his first year as defensive coordinator, Leslie Frazier’s 4-3 defense experienced its share of ups and downs and finished ranked in the bottom of the league in yards allowed (26th), rushing yards allowed (29th), passing yards (20th), first downs (30th), and sacks per pass attempt (31st).
Buffalo’s historically bad three-game slide vs. the New York Jets, New Orleans Saints, and Los Angeles Chargers, when the Bills were outscored 135-55, is responsible for much of the ugly bottom-line on defense.
