Here's the thing Dave. I can get the line of thought if I was in a neutral area, Texas, Indiana, Hawaii, w/e. But I became a STL Rams fan. The city is close to me, literally and figuratively (some of my earliest roadtrip memories was me hanging out in the floating McDs near the Arch). I watched the STL Rams win a Super Bowl and got through 6 wins in 3 seasons. Marshall Faulk and Steven Jackson to the likes of Ken Darby and Keith Totson.
The city does mean a lot, and I have thought about any potential positives about being an LA Rams fan. I'm sure I"ll get over it, but man it'll sure be hard.
