There are still 4 weeks left. Even if we can't schedule anyone decent (I think we'll land 1 or 2 more opponents), chaos at the top can still happen. I don't trust Indiana, Northwestern, Iowa State to finish the season without a loss the rest of the way.
Miami, Notre Dame, Clemson, Florida, and Cincinnati have decent chances to lose (UNC, Clemson, Notre Dame, Tennessee/LSU, Tulsa x2 respectively). Granted Notre Dame and Clemson won't fall below us, the others COULD.
Chaos is our friend, and nothing goes with chaos quite like college football.
