I've heard a hundred different scenarios: Texas goes independent, Mizzou and Nebraska goes to the Big 10, and my personal favorite...the BIG 12 south joins the Pac 10 to form a super-conference.

If the south does join the Pac 10...well that would just be crazy. 

Think about Texas, Oklahoma, Texas Tech, Oklahoma State, USC, Oregon, Cal, Oregon State, Stanford, UCLA.  Definitely enough to rival/surpass the SEC.

Personally, I doubt anything that drastic happens.

Hooray! Now they'll be relevant!

Whatever scenario brings in more money is the one that will happen.

Texas isn't joining the Big 10.    University has already said that. 

Big XII commish, Bebee is probably the reason this is happening.   In short, the vote for +1 playoff system last year which would have doubled revenues was shot down.    NU was not happy the way the Big XII voted.   Big XII, Big East and ACC voted against.   thats what started this ball rolling this time, $$$$$$$$

   Notre Dame is the focal point of the Big Ten, if they can get Notre Dame to except, then they will not offer an invitation to anyone else.  ND would be the infusion that the Big Ten would need to get more dollars for their TV contract.

    SEC has offer to Texas to jump.   If I was the SEC, I'd hang Texas out to dry.    When the SEC expanded years back, it was for Texas and Texas aTm to jump, Texas backed out, SEC got Arkansas and South Carolina instead, and that did nothing to improve the SEC TV revenue.

   This boils down to strengthing the conference for TV revenues.  If Texas went to the SEC, Pac 10 would not take the other Texas colleges.   Nobody wants to see Baylor and USC or Tech and Washington State.
