Hello, I'd say the Oakland Raiders. There's a lot of contenders for this, but I say Raiders fans due to their loyalty. Sure they are often portrayed as all criminals, but even when the team has only one 3 games all season, they still pay their hard earned money to see the team play. They may not be the loudest, but they are definitely devoted.
Im pretty sure the NFL-Forums never has anything for the NHL... There was another NFL forum that formed S2?
