Don't get me wrong, I think there is value in cutting some of the fat off. Currently there are 130 division 1 teams. In the Power 5, there are 65 teams. I think you could still add more to that if you wanted to add some state schools in to be inclusive of most all states (just for fan sakes) but that number is more realistic than 130. So if by just maintaining the Power 5 is considered a Super League, then sure. I can see value there.
When Indiana has Indiana State coming to Bloomington , IU is cutting them a check. That is what the big teams are trying to get rid of. Sharing revenue with much smaller programs because everyone else is playing those cupcakes. When Indiana plays vs. Louisville or Notre Dame, those schools aren't paying Indiana to come to their place. To me, that is a black and white line that shows where one is providing value and the other is not. So I think the revenue Ohio State is getting is because they are riding the shoulders of the B1G. They get to play in the largest TV market (Midwest), and within that market, they are arguably the best team.
Let me put it this way, if Ohio State went to the SEC (or some Super League) and was no longer the perennial favorite to win the conference, do you think their value would take hit over time? Most certainly. Texas had an enhanced revenue deal with the Big 12 that also allowed them to maintain their own personal TV rights. The end result was the rest of the conference (aside from Oklahoma) was made to look like they weren't as valuable which made the conference become devalued. A rising tide lifts all boats applies here.
The point being, Indiana and the rest of the B1G teams would tell teams like OSU to shove it if they came around with that nonsense. The ACC in basketball has proven the more talent you have in one conference, the more likely you are going to have a historically good team become mediocre. Because there's no way for everyone to always win. What OSU has right now is a mutually beneficial relationship and the value of leaving the B1G for any reason is not the same as Texas and the much weaker Big 12.
