There is nothing left to say.
A bowl game is still likely, but a pleasant finish is off the board. 2015 is a season best forgotten. All of the positive thoughts can only be recaptured with Auburn shocking the world in Jordan's-Hare Stadium on November 28. And that isn't going to happen.
Playcalling. I don't know why Auburn abandoned the run. Maybe Georgia was doing something that convinced Auburn it could no longer run. I assume they did, and I assume men that know much more about football than I do tried to adjust to it and failed.
