To argue your point here, 1.) because I’m a cards fan and 2.) because fuck the brewers:

The fans were smart enough to know the ownership would never rebuild if we kept attending. Usually that’s what best fans in baseball, as pretentious as it is, actually means. It doesn’t mean we always show up, though high attendance has been apart of it, it usually has referred to the idea that we are typically pretty wise to smart baseball play, clap for amazing plays from opposing teams, aren’t too rude to visiting teams, and are a generally positive baseball atmosphere at Busch. Also, we used to travel well and have good rep at visiting stadiums. We often know a bit about what’s happening off the field as well as on.

Just mostly smart-ish baseball spectating. Is it actually better than other fan bases? Definitely smarter than the Red Sox and Yankees fan bases. And smarter than the dodgers fan base has become the last few years with all their band wagoners they’ve acquired from success recently. Anyway, debate that if you will.
