For years OSU has tried to spread the wealth around in football. They have played pretty much every in state D1 football school on a rotation and even given a home date to some of the schools. It was more a financial move by OSU to benefit the other state universities than it was a competitive issue. Before UC moved to the Big East there was no incentive to play a CUSA team over a MAC team.
I don't really know if there is a big brother little brother issue going on in Columbus. I know a few years ago when UC went undefeated in the regular season UC fans sure had a fun time playing that up. The bUCkeye State was in good fun until UF came along. I root for UC sports in every game except when they would play OSU. I would like to see a rivalry renewed in Basketball and even football for that matter. But as a UC fan I would also like to see UK and UC begin to play more often than once every 25 years.
