Could work if Minny and Indy are unable to play.

Fox gets to broadcast a game with winner takes all and plays for the BIG Championship. 

This gives OSU the six games it needs to qualify for the BIG title game.

A rematch between the 2 best teams in the conference.

Indiana gets a second chance to prove they belong in the BIG Championship by beating OSU. Playing a close game with OSU does not entitle Indy to play for the BIG title just because OSU didn't play 6 games.  

OSU gets a second chance to re-affirm it is the best in the East by putting Indiana away for good.

Great drama and people will watch.
