I don't agree with the idea that, because the Seahawks haven't won a championship there cannot be a rivalry with such a storied franchise as the 49ers, and also that the team is irrelevant. There is, quite clearly, a budding rivalry between the two organizations. It happens when two teams get hot in the same division at the same time. It's inevitable. Lets take a look at the facts here:
A. We hate the Seahawks fans.
B. They hate us too.
What more do you need for a rivalry? Granted there are other rivalries with the 49ers that I enjoy more, i.e. the Giants, Packers, Cowboys, but to ignore the fact that one is emerging between the niners and shecocks is just silly
