This really isn't a proposal, its an idea being thrown out there by sbnation. I think it has some good points, but it also has some negatives. The biggest is with no divisions, it would be possible to have 2 teams playing the last game of the season and then the very next week playing the championship game. I think there has to be some kind of plan to keep that from happening.
One plan mentioned to the SEC commisioneer was moving AU and Bama to the East and Vandy and Missouri to the West. The west would love it, but the west has won the last 7 SEC championships, no doubt it is the stronger right now, the East not so much. But it would keep the 2 main rivalries going because all teams would be in the east. Then there could be 2 crossover games per year. This would mean those of us in the East would have to step up our game, but why not, the west has stepped up their's since Saban came to Bama, they are dominating crossover play right now.
Another option would be to play 9 conference games with 2 rotating and 1 pern cross over schedule. Personally this is my choice and I think its a choice of many fans. I understand UK is trying to build their program up and it's probably not a great plan for UK, but for some teams it we have some pretty weak home schedules, especially us with the UF game in Jax. We never have more than 7 home games and some years when we are home for the UF game we only have 6 and it sucks when 3 of them are against directional schools, yet season tickets are priced like it was all P5 games. I wish we would got to home and home for the UF game, its always a home game for UF, half the distance and instate, almost like playing it in Atlanta every year.
I really don't know how quick anything can be done, I suppose the best thing to do is bring in a couple more teams and try figure something out with 16 teams.
