There are countless rivalries in sports, but none are as bitter as the rivalry between the Eagles and the Cowboys. I know this because I am a lifelong fan of the Eagles. I have been going to games my entire life, and I have had season tickets since graduating from college in 1991. That gives me an up-close and personal view of the reason that this is such a bitter rivalry: Cowboys fans.
I can't even tell you that Cowboys fans from Dallas are the worst because I have literally never met an actual Cowboys fan from Dallas, Texas.
