lure enough schools to join them to collapse the Big 12, in my opinion. And the GOR will keep the schools from leaving for anything but the SEC or Big 10.

What you said is technically possible, but only if the PAC grows to at least 18 schools. And BYU would actually probably be one of the schools the PAC poaches if it does somehow get enough Big 12 schools to join it and dismantle the conference.
