The Big 12 needs to kick out U of Texas, talk Texas A&M to returning, calm OU & OSU, then add Florida State or Clemson as its 10th member. If they want to go back to 12 or more teams they can add them in future years.
The conference must get rid of the cancer that has caused it problems. That cancer is Texas. Hopefully it is not too late.
OU & OSU will be sorry they went to the Pac 12. It will do major damage to their programs. Baylor, Kansas, KSU, ISU, Mizzou & TTU all run the risk of ending up in a 2nd tier conference. What is required is fix the conference they have, and net leave their future it to the mercy of some conference officials on both coasts.
