I don't know who you are talking to, but I happen to be friends with IU, Louisville, and Kentucky fans. UL and UK hate each other with a passion, and IU and PU are definitely rivals no matter how bad one of them may be.
In the case of the OVC there are 9 football schools, and of the three that don't play (or play PFL) two of them are public schools. Throw us in the mix and there would be 10 football schools, 2 non-fb publics, and Belmont. That's a definite improvement for us in terms of playing against common opponents with similar agendas. It's better than playing 5 non football private schools with two of them that don't even have a baseball team. In the case of Belmont if they hated football as much as the private schools in the MVC the Bruins would have bolted both times they had an offer.
