Good point. It's just how you choose to view a rivalry against a team. More recently, the Cardinals have face the Mets in bigger games then the Cubs. Right, but that's seemingly different than the Cubs/Cardinals rivalry. The Cubs and Cards have such a long history and they play each other so often and they essentially share the same "home area" once you're outside the Chicago area. I'm not saying that the Mets and Cards playing each other is meaningless, because you'll still find plenty of Cubs fans that view games between the Cubs and Mets as a big deal, but it's simply not the same as what exists between the Cubs and the Cardinals and their fans. In fact, they way you're coming at this makes me think of how one-sided the non-rivalry between the Cubs and Brewers is because it seems like many Brewers fans are trying to prop it up into some kind of big deal while most Cubs fans don't look at it as much of anything unless both teams are in the playoff hunt. If some Cards fans are looking at the Mets as their "new rivals," well, it's definitely one-sided. I mean it like this. The Cubs-Cardinals rivalry is big and has tradition. It's a huge rivalry, I admit that, but look at the schedule now for 2010. The Cubs don't play in St. Louis until August. The Cubs and Cardinals don't play until May 28th, unlike when they usually play in late April/early May. Wait the schedule makers are in on this too? What does when the Cubs and Cardinals play have anything to do with the amount of rivalry these teams have? Also, do you think the Red Sox and Angels are bigger rivals than the Yankees and Red Sox? Because the Angels and Red Sox have been playing huge games a lot more recently than the Yankees, and also the Angels and Sox squared off in a 7 game series in the 80's too. Like you said, rivalries are in the eyes of the beholder in many ways, but a large majority of cardinals fans hate the cubs and a large majority of cubs fans hate the cardinals. Thats how it has been and how it will be. That doesn't mean you aren't allowed to have other rivals like the Mets. I mean hell the Cubs claim to have a rivalry with the Mets dating back to the 60's. Many older Cubs fans hate the Mets almost as much as the Cardinals, Ron Santo even more. But in general, the Cardinals and the Cubs are each other's biggest rivals. I think the Cubs-Cardinals rivalry is the biggest one in the NL but the Cubs, along with the Cardinals, have up and coming rivalries.
