Here are how I see the four spots broken down:
SEC Champ (13-0 Georgia or 12-1 Alabama) Top 10 game
PAC Champ (13-0 Washington or 12-1 Oregon) Top 5 game
Michigan if they win (13-0 Michigan is in 12-1 is out unless FSU and Texas lose) one team is not in top 10
FSU if they Win (13-0 FSU is in, 12-1 is out) one team is not in top 10
Next up if Michigan and/or FSU lose:
12-1 Texas
12-1 Georgia (if it was close)
12-1 Michigan (if it was close)
11-1 Ohio State
12-1 Washington (think of the dumb and dumber gif, "So you're saying there's a chance")
No chance:
11-2 Alabama
11-2 Oregon
Iowa
Louisville
We could possibly jump a 12-1 Alabama or 12-1 Oregon if they look bad while winning a 12-15 OT game and we crush Oklahoma State.
Oklahoma state is ranked too low and does not help us as much as a game against a top 10 OU would but everything else being equal that doesn't really help this year over the advantages we already have.
