I cannot stand Ohio or just about anything in it or from it, so I always root against Ohio State.
I've witnessed Penn State win a national title (January 2, 1987, against Miami at the Fiesta Bowl in Tempe, a day after I saw ASU beat Michigan in the Rose Bowl in Pasadena), so I'd rather see someone new win it.
I grew up Catholic so I cannot root for Notre Dame. Was sick of being told by several sisters and priests that we MUST cheer for
Notre Dame. Turned me against them at a young age. Plus, I witnessed them win a national title also - the 1989 Fiesta Bowl in which they beat Major Harris and the West Virginia Mounrtaineers.
Guess that means all I have left is Texas. Have been there a lot. Have friends and family there so it is fitting.
Interesting trivia: Will Howard, Ohio State QB, has never beaten Texas - in four tries. He lost to them three times as the starting QB for Kansas State and another time was watching from the sidelines as they lost to Texas.
Here's to adding one more loss in that streak.
