Buffalo Bills defense not better, but certainly different, in 2026

Buffalo Rumblings writer Bruce Nolan argues that the Buffalo Bills defense has regressed statistically in 2026 under new head coach Joe Brady and defensive coordinator Jim Leonhard. Through the first six games of the season, Buffalo ranks 30th in EPA per play allowed and 28th in EPA per dropback, representing a steep decline from the unit's pass defense numbers under former head coach Sean McDermott.

According to Nolan, the unit has shifted strategically to running base personnel on 36.2% of snaps while leading the league in Cover 4 usage at 26%. While heavier box counts have slightly aided run defense, Nolan notes that reduced coverage diversity, lower press rates, and poor communication have resulted in frequent explosive plays despite the Bills holding a 5-1 record heading into their bye week.
