This post is an example of what it would take, but it's never going to happen. If the fanbases of all these schools that could be left behind never tune into ANY of these Big Ten or SEC games, then things would have to change. Problem is you won't have that happen, as many people who say this are just blowing smoke and never commit to not tuning into the marquee game (Bama/Georgia, Oklahoma/Texas, etc. etc.).The networks are taking a calculated risk that the eyeballs and ad dollars they gain by more frequent marquee matchups will outweigh the loss of viewership from casual fans of schools like ISU who are on the outside looking in. They're gambling that fans like us are bluffing when we say that we will turn away from the sport.
And they might be right. College fans are super loyal to their schools. If our future TV payouts don't crater entirely and we still have a path to the playoff - both are those are very big 'ifs', but for the sake of argument assume they happen - most of us will probably talk ourselves into sticking around. And if we're going to watch our team, we're probably going to watch other teams too.
It would have to take every diehard and casual fan for these forgotten schools to make any possible dent when you couple that with the younger generations turning away from sports at a faster clip then previous ones. Millennials were crucial for the boom in sports, but data shows Gen-Z is drastically different by 10+% in sports viewership.
