Scenarios:
Currently, Vols are the 9 seed. If we beat Vandy, this is almost our floor, because it is very unlikely a team can jump ahead of us without a different team falling behind us (ie TAMU winning sec and Georgia and Texas remaining ahead of us).
1) Big Ten champ
2) SEC champ
3) ACC champ
4) Boise State
5) Big Ten champ game loser
Each of the following could move us up:
1) Jump a big ten team - About 20%
Penn state losing to Maryland -7%
Oregon losing to Washington AND Ohio State -8%
Ohio State losing to Michigan AND committee jumping Tennessee over Ohio State - 0.00%
Ohio state losing to Michigan AND Penn State losing to Oregon - 6%
2) Notre Dame loss to USC - 29%
3) Jump SEC team - 46%
Georgia loses to Texas - 46%
4) Jump second Big Ten team - 0.6%
Oregon loses 2, Penn State loses
Thus there is ~70% chance of Vols getting home field if we can take care of business this weekend.
And for those dreaming, the odds of the Vols getting the coveted 5 seed are about 0.05% (1 in 2000).
