I personally think that Clemson going undefeated and UofL going undefeated (with Chaos everywhere else) is your only hope...
FSU has now lost 2 games. Even if they win out, that takes the luster out of that win for you.
Houston needs Navy to lose twice in conference (which may or may not happen) for them to even win their own division. If they don't win their own division, that makes your win over them not as impressive either. Now if you add in Clemson face planting and losing two conference games that loss for you looks even worse and IMHO, the ACC is probably on the outside looking in for the playoffs (again, barring chaos everywhere).
Simply having chaos everywhere is your best bet...
