Redskins-Cowboys started in the 1970s when George Allen was the Redskins' head coach, and got huge in the 1980s. There may be some NFL rivalries that are as good, but there are none that are better. Certainly better than Ravens-Steelers (which started in 1996) and Manning-Brady (which isn't really a rivalry because they don't play each other directly).
My grandparents have been lifelong Redskins fans, and they've always gotten geeked up for the Cowboys in a unique way. I can get the respect vibe though.
Maybe it's because my grandpa is from Texas. There's no zeal like the convert.
