My dad and grandfather went to Michigan so I grew up as a fan (obviously I became a Texas fan when I went there). I almost went there myself, so take my 2 cents with a grain of salt.

I understand that a lot of Michigan fans probably seem stuck up to neutral observers, but I feel like many flagship schools (including Texas) are in the same boat. Plus, Texas and Michigan were struggling for so long recently I feel a sense of solidarity between the two programs. They even have their OU (OSU) and A&M (MSU)
