If Clemson or Bama lose then Stanford would probably be the favorite to get in assuming they beat USC (leapfrogging tOSU in the process). If they lose to USC or if both Clemson and Bama lose then it opens up the door for tOSU. If Clemson, Bama, and Stanford all lose then who knows. North Carolina? Florida State? Michigan State/Iowa loser? Clemson?
