Yep. The big boys left the B12. Now the big boys are fleeing the PAC. There is no reason not to expect the same to be coming for the ACC. The B12 should be in a position to become the best landing spot for anyone who doesn't land in the B1G or SEC. We should be reaching out to any Pac or ACC school who would allow us to maintain or increase our revenue as all this is playing out.To add to your point, if those schools added value for the big 12, they probably would have been added in the last decade at some point, or at least would have been considered in the last year. Any MWC school would have jumped at a big 12 offer, and will continue to, so there's no rush to invite them anyway.
And yeah, there will most definitely be ACC scraps leftover that'll be better options once the SEC\BIG rip them apart. Louisville, Pitt, etc.
Solidify ourselves as the number 3 football league and maintain our hoops position and things will be fine for ISU. Sure we would prefer the B1G invite, but being in a clear 3rd strongest conference would be much better than the doomsday scenarios we have stared down in the last decade.
