I think after awhile people are going to realize there aren't many schools that can "buy" a championship and the money will start drying up. NIL is still pretty new so people will see what kind of bang for their buck they will get but even donors at schools like Ohio State eventually are going to grow weary if the millions in NIL they cough up don't result in consistent Big 10 and National championships. Losing 3 in a row to Michigan now probably has some donors peeved too that they aren't seeing a return on their investment at the moment.
Realistically I get why people push the NIL narrative that we need to keep up to stay competitive but let's face it, the kind of guys we are trying to retain or recruit with NIL money aren't exactly 5 star recruits or the top guys in the transfer portal at the moment and even if we were able to get into that market you still have to go up against the traditional power schools to land those guys. Not trying to be negative but that's just the reality that even at ISU you probably couldn't go out and buy a national title in football even if you had the money available to attempt it
They'll fire a coach first before they look inward at their own decisions. It's similar to pro sports, it's not the players the GM brought it, it's the coaches fault for not using the players correctly.
