It doesn't take a genius to figure out where this is leading. The Pac-12 and Big Ten have maintained that they want a playoff, but only if they can maintain the integrity of the Rose Bowl. The only way to do that is for the Rose Bowl to become one of the national semifinals. This SEC/Big 12 Bowl becomes the other. Only four conferences really matter. They pick off the valuable properties that are left (Florida State, Virginia Tech, Notre Dame, etc.). Those four conferences control everything, and college football is effectively split into two tiers.
It'll take a couple of years for all of this to play out, but its coming.
Viva la superconference.
