I have the luxery of choosing what team to go for, as I am from Oklahoma and we have no pro team. A while ago I was watching a Chiefs Colts game and decided to go for the Chiefs. When the Colts won I was upset, the Colts advanced and played the Steelers, when the Steelers won I decided I really liked them. The next year they went 13-3 and I was happy, then they went 9-6-1, then they went 6-10. I considered switching teams, but then they went 15-1, and I am happy, as a side not, I now like the Colts as well.
I was born a Vikings fan. It's been a pretty "tough row to hoe". My wife says it's harder being a Vikings fan than being a Cubs fan. Ouch.
