FWIW, my secondary teams are places I went to school or worked at, plus the grad school of my lovely wifita. So, Virginia, Georgia, Virginia Tech, and Oregon State ... at the D1 level anyway. But, honestly, I don't really care what happens to any of these teams beyond when I look at the scores and come across who they're playing, and I have this mild little thing inside that says "oh yeah!" when they're ahead or have won, and "darn it" when they're behind or have lost, and then it's kind of instantly lost.
It's not at all the same as that gut wrenching feeling of despair that happens when the Sooners hang an L, which lasts like up to maybe 24 hours before I manage to remember that it's only sports, and so aw f--- it, there's always next game/year.
