The head-to-head result should be the tie-breaker when comparing two teams who have the same overall record, and the same conference record, with a similar strength of schedule. Comparing losses is unnecessary when there is a head-to-head matchup to consider. So what, that it could have gone either way? Tennessee should be ranked ahead of Alabama. PERIOD.
Having said that, I don't think it will matter much. Georgia, Michigan, TCU and USC should all win this Saturday and that's your College Football Playoff 1-4. Tennessee should get an invite to the Orange Bowl ... and if that is how it does play out, we should all feel a lot better about the loss to South Carolina. It will not have ended up costing us the CFP #4 ranking. USC would have jumped us, even if we had blown out South Carolina. USC as the 12-1 Pac 10 Champion, was never going to be left out of the CFP. Not a chance.
