Football Outsiders’ Scott Spratt analyzed each NFL team’s success in 2018 when pressuring via a four-man front, blitzes, two- and three-man fronts, and defensive back blitzes. It is judged based among the frequency, pressure rate, and DVOA. The Buffalo Bills finished amongst the NFL’s best in most categories.
Football Outsiders judges success rate partially on their metric DVOA. In layman’s terms, the statistic tracks every play from a given NFL season and compares it to the league-average for an individual situation. It measures yards towards a first down, on every down, and the crucial red zone yardage on downs — with an emphasis on it.
