In my opinion if there's any heated rivalry for the niners at this point in time it's us and the Cardinals. The Seahawks own us, the Rams don't pose much of a threat, we rarely play the cowboys anymore, I've gotten over my hatred for the packers for how they use to violate us in the mid to late 90's just becuase I got mad respect for Brett Favre and we hardly ever play them. I know the corss bay rivalry between us and the Raiders will never die and I hate their fans with a passion but, lets face it were not even is the same conference that's more of a territorial thing. But we've had some damn good matchups against the Cardinals over the past few years.
