I lived in Missouri for seven years and saw the Raiders play in Arrowhead several times and while they had our number for quite some time,we got some sweet wins in that stadium. But the fans are just the strangest lot I think there is in the league. I wouldn't call Chief fans football fans, although knowledgable. They are just Chief fans, if their team sucks, they turn off the game and go mow the lawn. They don't really get into other teams or players, just their own. I see the Raider Nation as the most die hard fans in football, but I see us as very competent football consumers. Here is a great look at the rivalry between the Chiefs and Raiders.
