I see one of two things happening in the future for college football as it pertains to the MAC.
1) Some kind of anti-trust situation gets pushed such that the "Power 5" are forced to allow all conference champions into their little playoff, and thereby allowing some sort of more equal sharing of the giant TV ad dollars.
2) The MAC, and other conferences like it eventually give up the ghost and drop to FCS, where the dollars invested may not have to be as significant. Granted, I know absolutely zero about the way dropping could affect expenses, or the bottom line. Personally, I'd still go to home games often, because I'm there for the full game day experience more than just the game.
Here's the problem with anti-trust. It's a hollow threat. Just because some Utah politicians scream it when convenient or the Boise President keeps yelling it doesn't mean there's any substance.
Here's the reasoning. The G5 are voluntarily aligning themselves with the P5. Nobody is holding a gun to their head or coercing them to sign onto these agreements. Right now, the G5 are 100% free to break away, form their own playoffs, line up their own venues, get their own television deals etc. Now, if hypothetically, the P5 used their market sway to stymie the G5 with playoff venues and television contracts--say went to the networks and said, "if you do business with these schools, you'll lose access to us" that is collusion and antitrust. That--in the absence of such collusion--the G5 product wouldn't be worth anything to the networks is not antitrust. It's market economics dictating price. I'll also bet that the bean counters at many a G5 school have come to the conclusion that the G5 schools are better with what they're getting from their arrangement with the P5 than they would be breaking off on their own. Again, that's not some insidious antitrust scenario; it's market economics.
Now take into account that the US largely stopped enforcing the Sherman Anti-Trust Act in the 1980s, and it's a policy that's been upheld by both Democratic and Republican administrations, clinging to the antitrust is fool's gold for anyone thinking it will lead to some playoff access or equal revenue sharing.
