Anything can happen in one game, but getting worked up over possibly 2 sec teams getting into the playoff, is like postulating that you may get hit by a bus tomorrow and then you get sued by the bus passengers for emotional trauma due to witnessing the event.
I think Georgia has as much of a chance to beat Alabama as Pitt does Clemson. Neither will happen.
The only drama for the playoff will be between Oklahoma and Ohio State (granted they both win)
