OU will not vanish from the CFB landscape. They will however, as all other schools including Texas, have to survive in CFB 3.0. The SEC is not going to allow any one school an easy path to annual or near annual conference championships. Barring a fall of some of its powers, there won’t even be terribly easy paths for traditional powers even to play annually in the CCG. OU brings reputation and institutional commitment, but memory can be short, and many schools want to win. Going forward, getting Jimmys and Joes is going to depend heavily on a well-managed and funded NIL and portal operation. A Wilkinson-style desk full of cash helped launch some programs, but neither OU nor aggy nor even Bama can coast forever on that part of their past. OU may turn up a billionaire angel to keep them competitive— who knows. The day before our first B12 meeting against Nebraska, few would have predicted that they’d be in a ditch and the LA schools joining them in the B10 25 years hence.
TLDR: OU has an enormous beta, both next season and long term. They are not a giant or terribly wealthy school.
