ND's ability to fundraise blows away most schools. That being said, how much of that pie goes towards athletics?
I think it's going to come down to future scheduling, access to a playoff, and having a suitable home for Olympic sports.
I think ND will stand pat for now and plan for multiple future contingencies. It will probably be some some poor shit hole school like FSU that will make a move that eventually leads to ND having to make a choice.
