I would say less than 50%. I really don't think that the Big 12 really wants to elevate more G5 teams if they don't have to. I think they are still watching the ACC to see if anything happens there, though that looks less likely than inevitable at this point.
What the Big 12 needs is more quality football. I think they hit the pause button on that UConn deal mostly because of the football program not doing anything to help.
Now UNLV is in good standing right now. Good market with bonus points for fans who want to come here for conference games. Just finished in the final comp rankings.
We did have our best year ever after being one of the worst FB programs in the country. We lost our coach and a vast majority of players that got us there.
Mullen was a home run hire with a contract that is P4 level. His buyout was purposefully low so you can't count on him staying IF he can do as well or better. Oh yeah, it is getting even more difficult to compete with power conference teams for players with NIL blowing up like it has.
So for UNLV to get that call they have to stay a top 25 level team for a few years, it would really help to crash the playoffs, and then we have to hire another homerun and start over from scratch personnel wise yet again most likely.
Unless the Big 12 gets desperate and they have another subpar year next season, AND UNLV not only keeps pace, but somehow does even better, then a call may come sooner than 6 years or so.
Which makes it tougher because we will be playing in a weaker league after next season and our degree of error becomes razor thin.
