The Big 10 has had a massive cash advantage over everyone in the Big 12 outside of OU and UT forever. While the absolute dollar amount difference is unprecedented, the percentage difference is nothing new.Unless the SEC/Big Ten add every single significant program in Texas and Florida there will be teams outside those two conferences occasionally rising up and playing very elite football despite any media cash disadvantage.
Of course the same could occur with other programs in any state who have the right coach and fan/alumni support...but I don't think it's even particularly difficult for programs like Baylor, Houston, TCU, Florida State, SMU, Miami, UCF to field very good football teams without the SEC/Big Ten advantages. Even a place like Cincy or Pitt might deserve mention here because Ohio State and Penn St can only take so many local top recruits from those high talent states.
The other way to end that "rising up" reality is to literally breakaway where Big Ten/SEC teams don't play anybody else at all anymore.
If we've learned anything during the last couple decades is the marginal benefit of that money is pretty damn small these days. The game changer would be if schools figure out a way and have the willingness to play ball with collectives and divert donors to NIL. But we're seeing ADs like Iowa wanting or having to stay disconnected. Whether it's that they don't want to give up their donor funds or that they are concerned about collectives essentially looking like a money laundering avenue to shovel funds to FB and MBB around Title IX.
