The final player is one that I think the Buffalo Bills really want to find a way to keep on the 53-man roster but would deviate from how the team has constructed their roster the past few years. Over the past three seasons, the Bills have not had more than six cornerbacks on the 53-man roster.
However, the Bills have realistically six players that are locks to make the roster with Tre'Davious White, Christian Benford, Taron Johnson, Dane Jackson, and Siran Neal. However, Neal is on the roster for his play on the performance and is not a better nickel than Cam Lewis.
If the Bills stick with six cornerbacks, they will need to get creative and that could potentially mean exploring a trade for Kaiir Elam. The former first round pick is probably the last cornerback on the depth chart at this point and doesn't look to be a great fit for the defensive scheme.
If the Buffalo Bills are not ready to move on from Elam, the team can certainly keep seven cornerbacks. Cam Lewis is not exclusively a cornerback and did spend some time at safety so he has some versatility.
However, keeping seven cornerbacks means another position loses depth that they have typically had. The Buffalo Bills are going to have some tough decisions to make over the next few days but these are four players who could surprisingly find their way onto the 53-man roster.
