Will the Buffalo Bills regret letting running back Mike Gillislee walk?

The Buffalo Bills have now lost yet another player in running back Mike Gillislee to the New England Patriots. Much like Hogan’s situation last season, the Bills decided not to match the offer sheet that New England gave Gillislee. While the Pats get another running back, the only thing Buffalo will receive in compensation is a fifth round draft pick.
