There is a tendency to think along the lines that there should be four pods of sixteen teams. That is fallacy thinking. If ESPN's goal was to get to four pods of 16 teams they will succeed when or if Tx and Ok become members of the SEC even if the B1G, Pac12, and ACC do nothing. They have sewed up the big goal of four (4) pods with 58 teams represented. I'll grant you that there are some teams that will get excluded from the 4 pods that are better than some in the four pods. However, those excluded teams still can make the expanded playoff by winning their way in. The biggest problem they face is "MONEY" . The TV rights for a newly constituted conference or a realigned conference are really impaired when you consider the population of the states involved. It is why the remaining Big 12 members are scrambling for spots that do not even exist, it is purely for the money.
If any conference has spots it is probably the PAC 12. The Big Ten and ACC need "NONE". There just are not any candidates for the Big Ten that can move the needle other than Notre Dame, which has a long term commitment to the ACC. Your only subtracting by adding, in a sense the law of diminishing returns. My advice don't get sucked into the idea that you need four pods of 16 teams. It isn't necessary. If you haven't read Frank the Tank article it is explained real well.
