I like the pod, as you play everyone at least every other year. Even with 2 divisions of only 6 (with a perm. cross rival), it can go 3 or 4 years before playing everyone. I rarely get to see a GT/Maryland game now. With 2 divisions of 7 or 8, it would be even worse. At those numbers, it might as well be 2 different conferences.
Evidently the Texas, Texas Tech, Oklahoma, and Oklahoma St. are Pac-16 bound, and they're going to do 4 pods as well.

Pod 3 - Washington, Washington St., Oregon, Oregon St.

Each team will play it's pod mates every year, and 2 teams from each of the other 3 pods.
