I totally respect that.
For myself, I was thinking "What other team that may modestly relevant could I see myself rooting for if not the Buffs?" I did come to a conclusion based on the following:
1) Accepted but did not attend
2) CU has played at least one epic game against them
3) My parents moved to that area for a bit
4) I did a campus visit as a part of their move
5) I saw them multiple times in person growing up as a part of my dad's efforts to acquaint me to spectator sports
6) My now ex-brother in law was a grad and huge fan, so I watched a number of games with him
The answer is Michigan. I know some will hate that, but I really don't give a ****. They are right outside the inner bubble, so I don't feel like I'm bandwagoning, and I've got enough ties to make it modestly personally meaningful. For comparison, I knew a guy who went to Kent State and was a huge Buckeyes fan and then rooted for the Cowboys because his estranged father rooted for them. Yeah, whatever.
Plus, Coach Khaki is always good for a few laughs each year.
I'm looking forward to it!
