2018, Supreme Court ruled that any state can legalize sport betting in the US.
2021, NIL is instated to allow college players to get paid.
2021, College football playoff expansion model is shared (review began in 2019).
2023-25, various tv deals expire for conferences and the playoffs.

And now we have OU and TX ready to move to the SEC. Given all of the various pieces, I think it is almost required for the PAC, Big Ten, and ACC to try for big moves. Not just to keep up with the SEC, but also to take advantage of the new landscape so that they can negotiate new tv deals. It's now big money for schools, for players, for businesses, and for states (with the gambling).

As such, I see several power moves available for the various conferences. The ACC is in the weakest position from what I can tell. The ACC is ripe for poaching (especially some of the newer members).

SEC: Could go to 18 and also grab Ok St, and maybe poach a fit like Louisville (natural rival to existing member but not a major threat).

PAC: Take Baylor, TCU, TT at a minimum. Possibly Ok St to get to 16 (or BYU). If everyone else goes to 18 then they could promote two from the Mountain West.

Big Ten: Rivalry play, grab Iowa St, KU, KSU. And maybe poach a fit like Pitt (in conf footprint and not a major threat).

ACC: Pick up WVU. Possibly promote 1-4 of UCF, Cincy, Memphis, and South Florida.
