There's no doubt that in this case Iowa doesn't make the cut.If the Big 10 and SEC formally separate from the rest of the sport, it's pretty obvious that it will only be a matter of time before they jettison the non-blue bloods and end up with the 16ish schools that are actual annual powers. Ohio State and Michigan are going to tire of subsidizing eventually.
Iowa and Nebraska won't make that cut.
But I don't see a 16-team superconference with nothing but bluebloods ever happening. Eventually half of them will no longer be bluebloods, they'll be the bottom half. And then why wouldn't the top 8 do the same thing all over again... why are we subsidizing these 8 bottom feeders?
Conferences need cannon fodder to help prop up the elite programs.
