‘His signing would seemingly make it unlikely that the Bills would retain cornerback E.J. Gaines, who is due to become a free agent next month. Gaines joined the Bills last August as part of the trade that sent wide receiver Sammy Watkins to the Los Angeles Rams. He started 11 games opposite rookie cornerback Tre’Davious White, who started 16. Gaines played well enough that he likely would attract some attention in the open market.’
