They probably wouldn’t join if they got that. They’re in a special situation compared to virtually everyone else.
It's a situation permitted by what has consistently been beyond feckless "resistance"- see the ACC dealing with them during Covid.
IF the B1G reallllly wanted to force the hand of these Irish hypocrite clowns and start using the stick instead of the honey then they could essentially end this independence nonsense in like a day.
You quietly go to them and simply say that as of a certain date no B1G member school will schedule you in football again unless you join the conference and we even may buy our way out of some currently scheduled games.
Who you going to play, toughguy? Not USC any longer. More than likely you won't even be able cry to any of the marquee ACC schools because that conference is dead. You going to join the SEC to spite us? Please. You know your fanbase wouldn't even accept you being forced to try to schedule an entire "independent" schedule with SEC filler after you play the service academies and Boston College (soon to be of the Big 12).
You going to cry to the TV networks? You don't think Fox is completely onboard with forcing your hand. You think NBC is going to give you moarrrr money when you're finally being iced out? ESPN? You had your chance with them when you were being begged by the ACC to join.
Soooooo....your little run of thinking you call every shot is over now because it finally dawned on us that WE control YOUR destiny unless you guys want to start calling Arkansas to see if they're interested in a home-and-home.
We can pick this up next time and start discussing how your influence with the Playoff system is going to be changing OR we'll just send you those B1G uniform patches over now so you can have them ready to be sewn on in time for the 2025 season.
Good day, sir! You get nothing!!!! (Aside from a full conference share and probably super preferential conference scheduling).
