'Gaines was given a cumulative grade of 87.4 for the entire preseason. Considering how topsy-turvy the offseason was for the fourth-year corner, the figures are very impressive. Gaines’ first game for the Bills came against the Eagles, and he had three tackles, two pass break-ups and an interception. His second game against the Ravens was equally notable. He ended with a tackle and a pass break-up, as he started to garner more starting time.'
