‘Gaines may be the toughest decision and situation facing the Bills as far as their own free agents this offseason. They were a much better defense and overall team when he played last year. His presence allowed others to play more natural positions and the defense to play more diverse coverages. In fact, the Bills were 8-3 in games Gaines started. They were 1-4 in games he didn’t. But that’s where the issue comes in. Gaines, acquired by the team in a trade for WR Sammy Watkins during the preseason, missed five games with injuries. He also left three other games with injuries. That’s half the games the Bills played that Gaines either got hurt during the game and didn’t finish, or didn’t play at all.’
