They almost did last time. Now Texas A&M is apparently considering jumping to the SEC once more.
People close to the situation say at issue is again the private TV network run by A&M's fiercest rival, the University of Texas, which apparently is going to function the way everyone feared it would -- as one long infomercial for UT. So A&M is in a snit and looking elsewhere.
Truthfully, it wouldn't be a dumb move. Think about all the extra coin that would be forthcoming from a conference that every year seems to have at least one team in the national championship game and several teams in the high-dollar BCS bowls. A&M might get a few more lumps pounded on it in the SEC, but I'm told dollar bills make a soothing balm for all the bruises.
You've got to wonder, though, if an A&M departure wouldn't begin the rockslide anew for the Big 12. Oklahoma is the key. If the Sooners would bail to, say, the Pac-12, the Big 12 is toast.
