It doesn't help either school. They don't really go after the same recruits, so no help there. One of them has to lose, so no help there. 

It's the same reason Urban said he wouldn't play Utah when he was tOSU. There is no point. tOSU beating Utah doesn't really help tOSU out in any way and he'd give Kyle a loss, which he didn't want to do. 

I highly doubt we see Utah and USU play anytime soon, especially as long as Gary is there.
