The Dodgers–Giants rivalry is the longest-standing and one of the most storied rivalries in the history of baseball
The Yanks/Sox rivalry is probably the biggest rivalry going on today because of the media and recent post-season games, but overall throughout baseball history it's gotta be the Giants/Bums for the best rivalry.
Originally posted by Ninerjohn: I think its Yankees-Red Sox for sure. I dont think there is one FB rivalry that even comes close to that. Niners-Cowgirls was big at one time but not anymore. I would probably put Lakers-Celts 2nd.
Definitely not Cowboys / Niners. I hate the gurls & every 9er fan I know hates the gurls. But I've met a ton of Cowboy's fans and every one of them lists the Packers as their rival in the 90's. Ask them about current rivalries and they'll just list the other teams in their division. They hate us, but its not the same as our hatred of them.
