David Edwards
The final player on this list is unfortunately in a tougher position because he will lose snaps based on what happens at another position. The Bills this offseason need to find a replacement for Mitch Morse and appear to have two clear options in Connor McGovern and rookie Sedrick Van Pran-Granger.
McGovern was signed as a free agent last offseason and played the entire season at left guard. However, he has experience at center and all indications are that he is going to slide over to center this upcoming season.
If that is the case then David Edwards would be next in line to start at left guard as Sedrick Van Pran-Granger is primarily only a center from his playing time at Georgia. If the rookie impresses early in OTAs and training camp, the Bills should feel confident in moving McGovern back to left guard in a spot that he played well.
In that scenario, it would be Edwards who loses snaps and would return to being a backup this upcoming season.
