The Buffalo Bills have had one of the league’s pass defenses since head coach Sean McDermott and defensive coordinator/assistant head coach Leslie Frazier took over in 2017. Part of that is due to the duo’s scheme, but that scheme needs talent in order to function at its highest level.
The first draft choice McDermott made, given that it’s been widely reported that he had final say on selections and not then-general manager Doug Whaley in the 2017 NFL Draft, was to take the cornerstone of the defensive secondary. While they passed on some quarterbacks, the team landed a bona fide star in the secondary.
