The Buffalo Bills have some very tough business decisions looming once their playoff run ends and the offseason comes into effect. A pair of cornerstone defenders are at the forefront of conversations already, as their contracts with the Bills are set to expire in less than two months. Linebacker Tremaine Edmunds and safety Jordan Poyer are two of the best players on a defense that has puffed its chest as a strength since the two arrived in Buffalo. Poyer has had a career revitalization with the Bills, while Edmunds has blossomed year-over-year, continually improving throughout his five-year stint.
