The difference is that IU and UK have won many national championships and always make deep post-season runs AND they have traditionally been poor in football.
Meanwhile, an Ohio school has not won a national championship in 60+ years and Ohio State sucks up all the interest for dominant football.
Cleveland State, Can't, and Ohio all garnered national attention when they made NCAAT runs. Apathy is expected when we lose every major OOC game and post-season game outside of the MAC. To Joe Akron, we are a good team in a terrible conference, and that is supported every time we play external to the MAC.
KD always said that all that mattered was winning the MAC. I think he had it completely backwards. Win outside the MAC, then people will start to care.
