Only possible opponents are:
Michigan, USC, Iowa, Washington, Nebraska, Illinois, Minnesota, Northwestern, Penn State
OR
Pittsburgh, Virginia, SMU, Georgia Tech, Miami, Duke, Louisville, Wake Forest, Clemson, NC State, California, Florida State
OR
Notre Dame
Since Notre Dame will win and make the playoffs scratch them off.
Since Tennessee will beat Vandy, likely mark off the Music City and Dukes Mayo Bowls so scratch off the bottom of the ACC, Minnesota, NW and Penn State
So that leaves likely
Michigan, USC, Iowa, Washington, Illinois OR
Miami, Pitt, UVA, SMU, Ga Tech
I doubt a Florida bowl would match us with Iowa again for the 3rd time in recent history, and we have recently played Pitt and UVA and open with Ga Tech next season.
So my guess would be
Michigan, USC or Illinois (never played them) or Miami or SMU
