I disagree with this, on two fronts really. First, I love big OOC games. Yes, sometimes you lose them, but I love those games. But that's just my personal opinion on scheduling.
More importantly to your argument, though, I don't think we have to run the table to make the playoff. Let's say we lose one regular season conference game and make it to the SECCG where we play Georgia and win. We would be a 11-2 SEC champ. That's getting us into the playoff most likely. I know that there has never been a 2 loss team in the playoff but I remember the discussion that Auburn would make it in 2017 if they had beaten UGA in the SECCG, so who knows. This will be the last year that matters anyway.
