The OU-UF pairing has been a consistent prediction/guess from Ross Dellenger going back to spring of 2022.

It wasn't based on any inside knowledge, but on him trying to create a balanced mix of rivals, geography, and parity, also using the top 8/bottom 8 theory that everyone was using last year before Saban mentioned their competitive matrix that the SEC was using when he started his complaints about possibly getting Auburn, Tennessee, and LSU.
Not saying it won't happen, but it seems to fly in the face of what the SEC has talked about with regards to protecting actual rivalries.
UF has no shortage of them and it would be sub-optimal if we ended up with Oklahoma vs say one of Tennessee, LSU, or Auburn, though since UF has been a big proponent of making 9 happen, it could be our AD is being overly flexible for the league.
