Honestly don’t know. It depends on how they do. If they turn into a Boise State of 15 to 20 years ago they may have a better chance of not getting left behind in the future if there is a split, which is now more in question. If they fall on their face excitement will back down.
Some things that are most likely true. It is going to get more expensive in the future to move up, both from the NCAA fee and conference fee. There are too many schools wanting to move (Sac St, Tarleton, UTRGV, etc), willing to pay to get an invite for it not to keep going up.
it is better to be established in the FBS sooner rather than later.
The current situation was not sustainable. Half empty dome for playoff games told us that. Hearing donation commitments from major donors are significantly larger with the move up and would not be increasing with staying at the FBS level.
I think the other FCS Dakota schools will have to follow in the next 5-10 years and it may cost them double. Plus they will be playing from behind.
