as a Mo State fan, i think SLU is currently our only non-con rival since we dont play anyone else on a regular basis out of confernce. we are both in the same state, both are in non BCS multiibid confernces, , we recuit the same kids, we are both building new arenas about the same size, so we have a lot in common. The only difference is the public vs private thing.
We are also starting a 4 year series with Tulsa next season so that has some rivalry potential since we used to play them up until a few years ago.
