I would prefer an alternative version of history where:
Nebraska joins the Big Ten the same year as Penn St did, 1993. Big12 forms 3 years early and adds BYU as Nebraska's replacement.
Then change the CCG game rules in 1993 so that you don't need divisions to have a CCG,. You only need at least 12 teams total. So the BigTen, Big12, SEC,ACC and Pac all eventually have 12 teams and CCGs with no divisions.
Then move up the start of the BCS to 1993 so that the 2 best teams are always playing for the national championship.
