Not sure how you’re concluding that Campbell’s intent is to cap labor costs. House Settlement already did that and SCORE would codify House. And everyone wants NIL regulation except for agents and SCORE addresses that as well.I don't think billionaires are inherently evil, but as far as I can tell this particular billionaire's plan is to lobby the government to allow him to form a cartel, strong-arm other schools into joining said cartel, and using that power to increase revenues while capping his labor costs. He's no hero, he's looking out for #1.
Obviously it's appealing to ACC and B12 schools because we get in on the top floor and pull up the ladder behind us, but it's not very attractive to anyone else. Even if you throw the G5/6 some extra money for leaving them behind it'll get eaten up right away by inflated costs (if everyone gets more money everyone has to spend more money to keep up), and they'll lose exposure, which is their primary reason for existence. The top of the B10/SEC can afford the current system and are doing just fine. The bottom of those conferences lose out relative to everyone else in the P4. I don't think they'll come along willingly.
This won't get solved by brute forcing a solution that picks winners and losers. I'll start to have faith in a solution when I hear university presidents (not ADs) are getting together to discuss how the college sports business model can work going forward. And I don't think that will happen until ratings/revenues start to fall, which doesn't seem to be happening yet.
And you’re wrong about the top of the B10 and SEC not benefiting. They double their media revenues like everyone else would and would maintain their revenue advantages with an element of unequal revenue sharing based on TV ratings. And obviously G5 would benefit with doubling of their revenues as well and a separate G5 playoff would finally afford those schools deserved access to a national championship instead of the current BS with token CFP access for only one team that has no shot at a national title.
The only parties not benefiting from Campbell reform are ESPN and Fox which is why they are refusing to broadcast Campbell’s ads.
