Actually you don't know that because it was under a totally different system. It's based on a human panel now so you can't extrapolate results that way.
Alabama woulda made it based on the computers. And computers can't tell the difference between a flukely loss and an actual loss. I think a human panel woulda given the 2013 Alabama squad even more benefit of the doubt. They were the defending champs. They dominated the SEC the whole season. And they were #1 the whole season, not Florida State contrary to revisionist history now. They really dominated the game with Auburn as well. They were easily the best team that season IMO. Given how flukey that loss was, the playoff panel woulda definitely given them the benefit of the doubt. 2013 Alabama with 1 loss woulda been a LOCK.
the bigger question is who woulda been #4?
