It looks like the Big 12 is going to continue to change, thanks to Texas A&M's impending move to the SEC. The Aggies are finally getting out of the Texas Longhorns' shadow in the Big 12 - for better or for worse. Texas A&M's move will give the SEC 13 teams, which means that the conference will be adding at least one and probably three more teams to give it an even number.
↵If and when the SEC expands to 16 teams, we're going to be one step, if even, away from super conferences. The Big 10 has already expanded to 12 teams, ditto the PAC 10 turning into the PAC 12. The Big 12 now currently only has 10 schools, and once the Aggies take off for the SEC, it'll be down to nine, and should Missouri bolt for the SEC as well (as has been rumored) then the Big 12 will be down to eight schools, while the SEC houses 16.
↵Nobody knows for certain what's going to happen next. If the ACC does indeed lose Florida State and Clemson, then the Big East will likely be poached next for their football schools, which will ultimately lead to the demise of the Big East despite bringing TCU on board.
↵Here's hoping the Longhorns don't continue to schedule the Aggies once they're in the SEC, just for, if nothing else, facilitating the demise of conferences as we know it today in the NCAA.
