Interesting prediction from an NCAA insider (former NCAA president) on long-range "super conference" plan in story today in cbssports.com. It's a great read with some other food for thought on NCAA oversight.

If the inevitability is four super conferences, assuming some geographic alignment for travel purposes and population density, with 16 teams each, would we assume 1 for east coast (current Big East/ACC geography), 1 for southeast (current SEC), 1 for west (current Pac 10), and of course 1 for midwest (current B1G).
The smart guys running the power conferences are probably focused more on this as long-term strategy, instead of short-term A&M or similar tactical moves.
Once those dominos start falling sometime in near future, then we get the popcorn and watch the fun as ADs and presidents start their scrambling for the extra spots. Very high stakes.
