The Champions League broke away like 30 years ago, and honestly European soccer might be the closest thing we have in terms of imbalance of talent and resources, and it worked out ok for them. Then the top Euro clubs tried to to break off last year, and the backlash caused them to reverse course quickly. Even the fans of the teams didn't seem to like it. I think that's closer to what we'd have here, in that all of the P5 schools are in healthy shape, but then there are a handful of behemoths, and I simply don't think there is more money in telling Michigan or Notre Dame fans they are going to have to stomach 2-10 type seasons, but that every game will be against Alabama, Clemson, Georgia, etc...
