usually one team doesn't win over and over for it to be a big rivalry
We have been winning since Payton got here, before that they used to beat us. I believe they have the alltime series record against us. They are definitely our biggest rivals, no question, and it has been so fricking awesome to mop the floor with them and, oh yeah, win a superbowl over the past 6 years.
These two teams have a history dating back 40 years and the cities also have a history. Just because we have the edge the last 7 seasons doesnt cancel out the rivalry.
