This is pretty much spot on. I lived in St. Louis for about 6 years after high school my whole Mom's side of the family is like 6 generations deep there. This is Bill Bidwell and the Cardinals take two. Almost the exact same circumstances. St. Louis will not miss the Rams until they are gone, much like the Cardinals. Ironically, I was a football Cardinals fan when I was a kid. Neil Lomax, Otis Anderson... Good times. Then Bill Bidwell ripped the heart out of my chest and I picked up my Dad's team. Funny how things work out. Otis Anderson killed us in 25.
And it's not just Missouri, there is a huge fan base on the East side. Belleville, Alton, Wood River, Edwardsville, Troy, etc.
