"Continguous". "AAU". The SEC sounds like it is taking a direct page out of the B1G playbook. If that's the case, college sports are probably headed into 4 megaconferences. B1G, PAC, SEC, and the "Best of the Rest". I hope UConn can find its way into the B1G and likely could if things keep moving in the AAU-direction. The Best of the Rest conference would consist of ACC/B12/AAC/MWC leftovers. Best 16-20 gets in.
The contiguous thing for the SEC is meaningless if you've ever looked at a map....try to expand that conference without doing it in a contiguous manner. It simply can't be done, so I'd advise not to draw any conclusions about 'megaconferences' there.
And forget the AAU as it pertains to the SEC.
If the SEC expands, it really has to go in one of two directions.
1) Head north. North Carolina-Virginia. Upside, tons of people. Downside, these schools might have options.
If UNC, Virginia and Duke are going to move, they're likely more comfortable in a Big Ten that would then stretch from North Carolina to the New York metro area than they would be associating with the Mississippis of the world. That would leave the SEC with the lesser lights North Carolina State and Virginia Tech. That's not a bad deal if it meant getting carriage rates in two markets with 18,000,000 people.
2) Go inland. Oklahoma-Kansas. Upside, easy pickings. Downside, smaller markets and the State questions.
In a vacuum, if the SEC offers Kansas and Oklahoma, they're gone. In reality, what to do about Kansas State and Oklahoma State? Answer - probably nothing. If you're a politician in Oklahoma or Kansas, you likely face more backlash for blocking OU and KU than you do leaving the States to the wolves.
Whichever way they go, SEC expansion will set off Armageddon.
