The only team I root for that I don't have a tie to via having lived in the market is Norwich City. My ties there are ancestra, however, as I am about seven generations removed from the mayor of Norwich (Timothy Balderston, served as mayor in 1736 and 1751) on my paternal grandmother's side.
Not surprising. I grew up in the South Bay, and we had several family friends who were Stanford grads. They never considered Stanford the Cardinal. As far as they are concerned, they were still the Indians, and would always refer to them as such. When you go to Stanford games, a lot of the grads still don their Indians gear.
I can almost understand it when it's someone who actually attended the school before the switch do that; but being from Milwaukee, I'm familiar with guys who were in diapers the last time Marquette was known as the Warriors, but still insist on calling them as such. Of course, it never seems to happen unless the previous mascot was a non-caucasian caricature... no one ever refers to my school (UWM) as the Gulls, even though it's a much better nickname than Panthers.
YH and I both did graduate work at Oklahoma City University (he Law, me MBA)... neither of us refer to OCU as the Stars, but as the Chiefs.
