I know Chip Caray can be over the top when hyping things up during a game, as seen by this great link, but you've got to wonder how much hyperbole he can get into by claiming the Cubs-Cardinals rivalry is bigger than the Yankees-Red Sox. Maybe it's my New York/northeast bias kicking in, but it seems like Yankees-Red Sox has a lot more legs because it's actually very competitive on the field -- and has been part of some big games in history, like Bucky Dent.

I'm not debating Cubs-Cardinals isn't a big rivalry. It definitely is especially in downstate Illinois, but best in baseball? Hardly. It's probably the best in the Caray family since old Harry worked for both. But it's hard to call something a big rivalry when one team has won tons of pennants and the other is best known for being loveable losers. (Not just bad luck second-place stuff like the Red Sox.)
