Of the 9 teams below Miami, there are only two games that feature an opponent ranked inside the top 15. GT plays UGA and Vandy plays Tennessee. So if the teams below us win the games they should then you're looking at:
1) OSU
2) Indiana
3) Texas A&M
4) Bama
5) Oregon
6) Ole Miss
7) Winner of GT/UGA
In addition, you'll get a guaranteed spot for the BIG12 and G5 schools.
8) USF/Memphis
9) Texas Tech/Cincy/BYU
Then the possibility exists that Vandy beats Tennessee.
10) Vandy
That's a razor thin margin for the final two spots.
The nightmare scenario is GT beats UGA, Louisville goes undefeated the rest of the way, makes it to the ACCCG and beats GT. You'll have two ACC teams locked into the playoff that looks like this:
1) OSU
2) Indiana
3) Texas A&M
4) Bama
5) Oregon
6) Ole Miss
7) GT
8) Vandy
9) G5 Team
10) BIG12 Team
11) Louisville
The 12th spot will come down to Miami, Notre Dame, and UGA. That's not a fun spot to be in.
