much of the talk about the SEC is most unlikely. The contract SEC and television is for 11.0 M per team per year for the next 15 years. The Big 12 is about 8.0 m per team subject to renegotiation. If one looks at the intake for TEXAS 130 M per year. There is almost no attraction for Texas for the SEC and very little for OU.
Also schedules of 16 teams or 14 teams offer significant difficulties. The Big East in basket ball has a 16 team league. Each team plays one another 1 time and one game is played home and away. In football it would be dreadful = each year 7 games in a division and one game in the other division. this would mean match ups such as Ga and Auburn or Tenn and Alabama would occurr twice every 16 years , rather that twice every four years.
Simply put it is not going to occurr. The Big ten because of symmetry may add one team. IT would result in two rather unequal divisions - Ind, Purdue, Ill , Northwestern , Iowa and whoever. but 12 is a more convenient number than 11. One question is how much more would Mo and/or Neb add to the contract. - 44 million, I doubt it , 22 with Mo possible but unlikely.
A contract with the West coast two games each week per station a B -12 game followed by a PC game makes more since.
