My beef is not that Cards fans are arrogant because of their team's success(I don't really follow baseball, so I don't give a rip about their team), they're arrogant because they think being a Cardinals fan in itself is an achievement. They are the self-professed best sports fans in America, and they have no problem telling you what great fans they are.
Yeah, you know baseball Cardinals fans? You know who else knows baseball? Every 11 year old in America. Understanding baseball is not something to brag about.
Find me an 11 year old that knows what Yadier Molina's DWAR was this year. Find me an 11 year old that knows what a LOOGY is.
STL fans are a top 3 fanbase regardless of whether they lost this series. IMO you had maybe the 2 best atmosphere's in baseball going at it in the NLCS. Only other comparable would be Boston.
