The debate has already started, even though it’s probably not even necessary.
With Alabama, Florida State, Oregon, Ohio State, Baylor and others undefeated, there has already been much discussion about which teams would play in the BCS championship game if more than two finish the season unbeaten.
This is probably a good time to remind everyone that only twice since the BCS has been in existence have there been more than two undefeated teams at the end of the regular season from an automatic-qualifying conference (ACC, Big Ten, Big 12, Big East/American Athletic, Pac-12 and SEC). And only six times since the BCS was implemented in 1998 has there been a title game matching unbeaten teams.
Using advanced metrics, Bill Connelly, who writes the Football Study Hall blog for SBNation and is the author of the book “Study Hall: College Football, Its Stats and Its Stories,” determined there is only about a four percent chance Alabama, Florida State and Oregon will all get through their remaining schedules unbeaten.
So it is far more likely that the debate will end up being which one-loss team (or teams) deserves to play for the national championship.
The quality of a loss can be as important as the quality of a team’s victories. See Oklahoma State’s overtime loss to Iowa State in 2011 that kept the Cowboys from playing for the national championship for an example.
This week the top four teams in the BCS are all hefty favorites to varying degrees.
No. 1 Alabama gets Tennessee at home. The Crimson Tide have won six straight in the rivalry. The Volunteers are coming off their first big victory under coach Butch Jones, but beating Alabama in Tuscaloosa will be far tougher than it was to take out South Carolina in Knoxville.
No. 3 Florida State, second in the BCS standings behind Alabama, gets North Carolina State at home. The Wolfpack have been a nuisance for the ‘Noles in recent years, including last season, when they rallied in the fourth quarter to win in Raleigh.
Oregon, No. 2 in the AP poll and just a shade behind FSU in the BCS, faces No. 12 UCLA. The Bruins are coming off a loss to Stanford. Playing the Ducks and Cardinal back-to-back is generally not a recipe for success, as Washington can attest.
No. 4 Ohio State is home against Penn State. While Alabama is in the BCS driver’s seat — for whatever that’s worth a week before Halloween — and Oregon and Florida State are positioned to jockey for second, the Buckeyes appear to be stuck behind all three. They can least afford a loss if they want to stay in the race.
