‘At the top of the list is cornerback E.J. Gaines, who came to the Bills last summer in the Sammy Watkins trade from the Rams. Although Gaines battled injuries, as he has most of his career, when he was on the field he was a solid complement to rookie corner Tre’Davious White and helped the Bills’ secondary have a nice season. He will get offers, but given his injury history, his price may not be huge and the Bills would be wise to stay in the mix to retain him.’
