When we started this series, the conversation was concentrated on a little program shuffling at the FBS upper level (known as the Power 5) through four of the five conferences. The big concentration was on the action and activity going on in the Big XII as Texas and Oklahoma prepare to head to, the for-now, 16-team SEC. There were issues there, but nothing that hinted at the lower tier disintegration and cannibalization of Conference USA, the explosive growth of the Sun Belt, and then the scramble for the Big XII to repopulate its ranks with G5 teams that made sense in the Power 5.
