It was clear over the first half of March that the Buffalo Bills' focus was to bring back key players from last year's team whose contracts had expired and try to address some needs wherever they could with the limited salary cap they had.
However, this also meant that the Bills saw a number of former players leave and sign with new teams during the early parts of free agency. These players were big parts of the team over the past few years but when seeing the contracts they received, it is tough to blame the player or even blame the team for not bringing them back.
When looking at the contracts, it is tough to see how they will be able to live up to that salary and these are four former Buffalo Bills that might have expectations that are unable to be met.
