He contributed to the season, you can't do that. Would it be cool if the Bills had won the Super Bowl this season and they decided not to give a ring to Kevin Everett?
I've heard that the team gets to decide to whom they give Super Bowl rings. I heard this because last year the Colts apparently decided as a team to give Super Bowl rings to everybody, including administrative staff (secretaries), scout team players, a player that was cut by the team a couple weeks before the players in order to pick up additional depth at another position, etc. It seemed like an extremely classy move. They said that they won it as a team, and the whole team deserved the rings.
