No one knows what will happen but some interesting scenarios could be set up. Say Auburn beats Georgia (again) and that for sure would put them in the 4 team playoff. If then Ohio State was to beat Wisconsin, something very likely, then you would have Alabama setting at 5th place in the committee's rankings as of this week and the question would be would Alabama be strong enough to win out over a two loss Ohio State team given that Ohio State would have won the Big 10 divisional championship and Alabama wouldn't have even played for it's divisional championship.
Clemson and Oklahoma are most likely locks for the top 4 if they win their next games and Auburn or Georgia should be a lock if they win the SEC championship but I believe for Alabama to have a ghost of a chance to be chosen as one of the top four Auburn has to beat Georgia in the SEC Championship and Wisconsin has to lose to Ohio State in the Big 10 Championship. Then it all is a question as to whether or not Bama would get the nod over a two (ugly, big) loss Ohio State team. Also if Oklahoma was to lose it might could also open a chance for Alabama to squeak in.
Either way there is a chance that Alabama and Auburn could meet once again this season. If Clemson goes down to Miami and Auburn wins over Georgia then a #1 Auburn could possibly face a #4 Alabama. If Auburn was to stay #2 and Clemson #1 then the possible matchup would be a #1 Clemson in a rematch with a #4 Alabama. Then again as beaten up as Alabama ahs been and being defeated like they were against Auburn it's going to be a long shot for Alabama to recover enough to stand a chance against a team like Clemson or Auburn again.
And what's going on with Tennessee? No bowl game possible after quite likely one of the most dismal seasons ever and now the Athletic Director's first choice for a replacement head coach is as much as drummed out, by the fans and students, before he ever had a chance. Jon Gruden has been sold so soundly that anyone else other than him is going to be a major disappointment for many fans and students. Not only did Tennessee wait a while to get into the game for looking for a head coach but they allowed Florida to get Dan Mullen first and Kelly, who most likely never was a possibility, at Tennessee, goes to UCLA. Irony of all Irony there was many students seen carrying signs to bring back Lane Kiffen.
