I hate the Big 10, I don't mind the Pac 10 (or 12...I still call it 10)...I don't like the Big 12, or the SEC.
In football, I can't root for the SEC, Big 12, or Big 10. The Pac 10 is fun to watch at night, and I always find myself watching Hawaii Warriors games late at night.
I'm a Hurricanes fan for life though, they're my first love, and once they're out, then I just casually watch, but have that rooting guide handy in my head.
I'm much the same. I went to FSU and they are my first love. Once they are out of it, I mostly don't care but dislike some teams more than others. I do cheer for the underdog sometimes regardless, like Clemson and Georgia against Alabama.
