In terms of depth, the Buffalo Bills have been able to amass plenty in the defensive secondary over the last two seasons. Heading into the 2019 NFL season, the Bills appear to have all of the pieces a coaching staff could want at both corner and safety. The team has clear starters who are at the top of their respective positional groups when compared to the rest of the league, they have solid veterans who understand how to prepare for excellence week in and week out, and they have solid young athletes looking to make their mark in the league.
