That will never happen. The Big East with 3 schools left picked apart a
stronger CUSA. Too much money, even if the Big12 is down to 2 or 3 schools they won't leave the conference tournament and playoff credits behind.
That is why we need it to collapse and dissolve. All 10 need to find a home in the Power 4 or if 8 teams can leave all at once, they might have enough votes to dissolve the conference and not pay any exit fees.
