No matter how good the SEC is, Ohio State would deserve to be in the 4 team national playoff.
To make it simple: Every SEC team has a chance to win a playoff game called the SEC Championship game. That's your ticket in, if you didn't make it there or can't win there... why do you deserve to go to the national playoff for the National Championship? Even if it's a 1 loss Alabama, it means that they lost to South Carolina or Missouri & so they pretty much just lost a playoff game. If you didn't beat South Carolina or Missouri to cement your spot, why should they get another chance? There's zero reason for it, given that there's an undefeated Ohio State team out there that hasn't lost.
