The worst thing that could have happened to the SEC happened: a college football playoff.
While the SEC certainly earned hype, that hype eventually fed on itself and created more hype. The bottom line is that for the past seven years, the best team in the SEC was going to participate in the SEC Championship Game (and, in one year, two SEC teams). That was due to hype. Thus, the SEC has realistically had a 50% chance at winning a national title every single year; while other major conferences have been battling to put together a team to fill the second slot.
With four slots, it is going to be tough to justify giving the SEC two of them. Thus, a 50% chance is cut in half. And, moreover, a great non-SEC team that just happens to stumble once down the stretch will now remain in the mix (Oregon, anyone?) making it that much tougher in the postseason.
And, before anyone jumps all over this like gnats to ****, Alabama was by far the best team in college football in 2013. But, Oregon would have given them as much trouble as aTm, in my opinion.
