If we lose to Georgia, and Georgia runs the table, then Georgia will be in the SEC title game. The dawgs still have to play florida, mississippi state, kentucky, so they could slip up--but they'll certainly be favored in all of those games.
So then you could have unbeaten Georgia playing, say, one-loss Bama in the SEC title game, as I think bama will beat Ole Miss. (I'll be shocked if they don't). So then if Georgia beats bama in the title game, assuming we don't lose any other games, we should be in the playoff. But if one-loss bama beats georgia in the SEC title game, then we might have a problem. That almost certainly would ensure that both bama and georgia are in the playoffs, and the osu-michigan winner is going to be in the 3rd team in the playoff. And then? If Clemson is undefeated, then we'll probably get left out--as the committee will not put 3 SEC teams in the playoff, especially if Clemson is undefeated. There's also a chance a Big12 team (Ok State) could go undefeated--though they've got some tough games left and a one-loss UT ought to get the nod over a Big12 team.
Let's just keep winning and it will take care of itself. I think we'll beat Georgia, frankly.
