My first thought this morning is that we all need to be focused on the B1G reaction.
That conference has the most money, was the first to launch a network, has both ESPN and FOX behind it, and has been the most aggressive with expansion in the past. It also has been the only conference that has previously considered the idea of expanding to as many as 20 in comments by leaders.
If the SEC has actually meddled by taking "superconference" and trying to talk to Michigan & OSU, there's a chance at the following:
1. B1G poaches the SEC with offers to Missouri & Kentucky. (No GOR in the SEC).
That moves the conference to 16 while gaining MU-NU football rivalry, MU-Illini hoops rivalry & UK-Indiana hoops rivalry.
2. B1G is able to offer a 4-team package to the B12 to bring in KU, OU, ISU & UT to take the B1G to 20.
The B1G adds a bunch more rivalries (OU-NU in football, MU-KU in hoops, ISU-Iowa in everything, OU-UT in everything), and the conference pretty much maintains its culture of state land grant universities with AAU membership (only OU & UK fail to check both boxes).
B1G could them go East/West with:
East: Michigan, MSU, Northwestern, Purdue, Indiana, Ohio State, Kentucky, Penn State, Rutgers, Maryland.
West: WI, MN, Iowa, Illinois, ISU, NU, KU, Mizzou, OU, UT.
Expect the Big Ten to get very aggressive now. Also, their new media deal is coming up first so they have the most impetus to increase value.
