'Quarterbacks beware. Under the direction of Bills defensive coordinator Leslie Frazier and head coach Sean McDermott, the Bills defense has found itself in familiar and unforgiving territory, in a 4-3 defense. For Buffalo’s front four, this is great news. For their opposition, however, not so much. In 2014, the last time the Bills ran a 4-3, sacks were aplenty, totaling 54 on the season. Buckle up, Bills fans. You could be in for quite the ride on Sunday.'
