2.) Anthony Barr - Linebacker
Even though Barr is listed as an outside linebacker, if he is able to adjust to the defensive scheme that Sean McDermott is more than likely planning to run, Barr could be a good addition to a position that is a big question on the defense.
Sure, he may not be a flashy signing for the Bills but he would be able to provide stability at the linebacker position. The Bills currently have an on-going linebacker competition between Tyrel Dodson and Terrel Bernard. With Bernard dealing with a hamstring injury, this leaves Dodson as the leader of the competition but he struggled in the first preseason.
When the Bills face the Steelers for their second preseason game, if Dodson continues to struggle then the Bills may want to look at the option of signing Anthony Barr. In eight out of nine seasons, Barr has recorded 50 or more combined tackles in a season. If the Bills want to bring some sort of stability at the linebacker spot, Barr might be the best option moving forward.
