True, but the infighting might drive something to happen. There will be calls for unequal revenue sharing, renegotiation of TV contract, adding teams, anything they can throw against the wall. There could be a lot of acrimony, and that might be enough to make something happen. Even get 8 teams to work together to dissolve the conference (assuming 8 of them could find landing spots elsewhere, which is possible).
Zeroth law of economics: If something is unsustainable, eventually it will stop.
Clemson making half what Iowa State does is "unsustainable".
But Clemson making 1/3 of what Northwestern, Purdue, Illinois, Rutgers, Maryland, Vandy, etc. is unsustainable by that definition, yet it's been happening and is going to happen for a long time.
The thing is, if Clemson football just disappeared tomorrow, it would make almost no difference in the business of college football media. In the midst of a dynastic run they had primetime ESPN games against other ranked teams and would draw like 2M viewers.
So actually Clemson making 1/2 of ISU, or 1/3 of Northwestern is perfectly sustainable in the broader college football environment. Obviously Clemson could be highly valuable in the Big 10 or SEC. But it really isn't impacting the P2 to not have them, nor is it a problem for CFB.
It doesn't make sense that Clemson makes less than many of these teams, but a few teams being born on third base doesn't change the fact that Clemson is locked into a bad deal. And it doesn't change the fact that they STILL don't have a fraction of the value Texas has, yet Texas couldn't buy their way out.
