Looking at the new committee rankings, it seems pretty clear what they are going to do with the 4th spot.
LSU in even if they drop a game
Ohio State could drop a game and probably get in
Clemson in as they almost can't get beat in conference the ACC is a 1 team conference this year
Georgia in if they win out
Alabama in if they win out and Georgia drops a game
I guess the PAC season really did end win Auburn beat Oregon.
There is no guarantee that LSU is in if they lose this late in the season. They will most likely win out, so they're in, but if they drop a game, they should be out.
Ohio State most likely isn't going to lose, so they're in.
Clemson isn't losing a game, so they're in.
Georgia won't win out, so they're out.
If OU and Oregon win out, one of the two should get the last spot due to them winning their conference.
Alabama shouldn't make it in for not even winning the $EC West, not to mention not winning their conference. Also, their strength of schedule and quality wins is weak.
Here's where it would get fun and interesting, and would be the $EC's worst nightmare, although very unlikely. a&m beats Georgia and LSU. Auburn beats Alabama. Georgia beats LSU in the CCG. All of the top three teams in the conference would have two losses and no team from the $EC would make the CFP. Now THAT would be glorious, lol!
