The Pac12 isn’t going anywhere. If(When) UO,UW and the four corners schools leave, the remaining Pac12 schools will keep the conference alive and absorb whomever they want from the MWC (and/or other G5s). Until the various playoff and NCAA bylaws are revised, or there’s a complete schism into a Power 2, the Pac12 is still a Power 5 conference and gets the perks associated with that. By 2030, yes, it’s likely that the Pac12 will be relegated to G5 status, but until then, it still gets the playoff spot, it still gets to decide rule and regulation changes like a P5 school, etc…. It’s much more likely that the MWC dissolves and the members join the kneecapped Pac12.
