Don't care about other B1G schools at all
I confess that I do enjoy seeing other B1G teams beat the SEC! SEC! teams.
Both of these are true, for me. I don't know how. I can't explain it.
Until about 2014, I typically would root for Big Ten in neutral games. Except the cheaters - I didn't root for them. But that ended around 2014, when we'd get reports that the Big Ten was richer than other conferences. "So these Big Ten teams have more money than SEC teams, and they aren't spending it on the football teams?" I figured that Ohio State was the only one pulling their weight in the conference. So eff the other teams. At that time, I felt Ohio State and Sparty were the only ones playing above their level. And maybe I should have given credit to Wisconsin, at that time. But Illinois, Penn State, *ichigan, Nebraska.... they were all shitting in their bed. So eff them.
Today, it's still sorta true. Penn State has improved. Sparty has fallen back to where Sparty should be. *ichigan cheated their way to some success. Indiana is now WAY above their level. But Nebraska, Wisconsin - they're still shitting the bed. USC, UCLA - what are you doing? Time will tell if Illinois is as good as we thought they might be. Time will tell if the Big Ten can use their "richest conference" title to any good.
But yeah, I'll root for most Big Ten teams over most SEC teams.
