Minnesota, I think there's a greater mutual hatred between NU & Miami than any of those schools. Texas & Notre Dame don't really care about us and Oklahoma-Nebraska was never really about hatred. NU & Miami genuinely hate each other. Not sure we really have that with any other school.
The Dude- I think their is some hate from the fan bases, but neither team is that great.. and Miami fan base is hit or miss... In terms of environment, i prefer ok or ND, but i hear what you are saying about why Miami is a good fit.
