why are we everyone's Super Bowl?

We aren't.

It's something people say to excuse the good play of others and bad play on our part.

The Rams did not think we were their Super Bowl. They'd of much rather beat Seattle or the 49ers I'm sure.

That's debatable considering they pulled out an onside kick when they were up 14-0. Fisher wanted to stick it to us after Rob decided to go with us instead of them.
