Measuring the title contenders
A thrilling Iron Bowl victory by Auburn on Saturday shook up the BCS standings and left only two undefeated AQ teams at the top of the polls. The
Florida State Seminoles and
Ohio State Buckeyes appear to control their own destiny as they prepare for their respective conference championship games. But three SEC teams -- Auburn, Alabama and Missouri -- also are ranked in the top five in the BCS standings and are in position to seize a title-game bid if the Seminoles and/or the Buckeyes are upset.
Those five teams are all ranked highly in our
latest FEI ratings, although not in the same pecking order as the BCS standings. FEI is an opponent-adjusted drive-based system designed not to select a national champion but rather to measure overall team efficiency, the success of a team maximizing its own possessions and limiting the possession success of its opponents.
Team records are a function of performance and the strength of the opposition faced. Ohio State ranks ahead of Auburn in our FEI ratings, for instance, but, if the two teams swapped schedules, they likely also would swap records. According to our data, the Buckeyes would be 11-1 against Auburn's schedule and the Tigers would be 12-0 against Ohio State's schedule. (It should be noted that, in this alternate scenario, Ohio State would still be ranked just ahead of Auburn according to FEI).
The possession efficiency data is also useful in projecting what might lie ahead for the remaining BCS title contenders. We compared each of the top five teams in the BCS against every team in the 2007 to 2012 seasons across five key measures -- opponent-adjusted offense, opponent-adjusted defense, special-teams efficiency, field-position advantage and overall FEI rating.
Which teams from the recent past are most similar statistically to the BCS front-runners, and where might each end up when the dust settles this weekend?
Florida State Seminoles (12-0)
Most similar profile: 2009 Alabama (14-0)
Nick Saban's first championship team in Tuscaloosa ascended to the No. 1 spot in the polls only after an SEC championship game victory over Florida at the end of the regular season. Florida State waited its turn, as well, advancing ahead only after top teams with higher preseason ratings dropped off.
Like this year's Seminoles, the Crimson Tide played their best football in their biggest games that year, especially on the defensive side of the ball. Against four conference opponents ranked at the time of the game, Alabama allowed an average of less than 10 points per game -- Florida State is on the same pace heading into its ACC title game matchup with No. 20 Duke. Both 2009 Alabama and 2013 Florida State surrendered only 0.9 points per drive and allowed fewer than 30 percent of available yards (measured from starting field position to end zone).
The main difference between the two teams is the strength of the opposition faced. Including postseason games, Alabama played the sixth-toughest schedule according to FEI, and Florida State has faced only the 98th-toughest schedule to date. But despite being relatively untested, FSU has posted seven victories ranked among the top 50 in our opponent-adjusted single game efficiency measure. No other team has more than four such wins. There are multiple ways to impress as a legitimate national championship contender -- edge out a number of good teams, or destroy nearly everyone in your path.
Ohio State Buckeyes (12-0)
Most similar profile: 2010 TCU (13-0)
In most cases, the Buckeyes would love to be compared favorably with an undefeated Rose Bowl champion. But the 2010 TCU Horned Frogs were left out of the BCS national championship mix and Ohio State has no interest in following that particular path.
In terms of raw stats, this year's Buckeyes have more in common with 2010 TCU's offense than its other units. Ohio State ranks No. 1 nationally in avoiding three-and-outs, earning at least one first down on 84.1 percent of its non-garbage drives. In 2010, TCU ranked fourth nationally in that statistic (79.8 percent). Ohio State has scored 3.8 points per drive; TCU averaged 3.4.
When the 2010 season wrapped up, TCU had played only one team ranked in the final Associated Press Top 25, and that was its Rose Bowl opponent, Wisconsin. Ohio State might have a similar lack of ranked opponents at the end of this season. The Buckeyes should still be in good shape to claim a BCS championship bid with a win in the Big Ten title game, but they should consider themselves lucky that there aren't two undefeated AQ teams ahead of them.
Auburn Tigers (11-1)
Most similar profile: 2011 Oregon (12-2)
Like the Buckeyes, Auburn compares most similarly to a Rose Bowl champion that had hoped for even more back in 2011. The Ducks started the year as a preseason national championship contender and ended the year ranked No. 4, but two disappointing trip-ups in between spoiled an otherwise outstanding season.
Auburn has lived on the edge a bit more than Oregon did in 2011, but the overall résumé has several similarities. Both teams lost by two touchdowns to an LSU team ranked in the top 10 at the time of the game. Oregon lost 38-35 in mid-November to USC, but Auburn's miraculous tipped touchdown reception against Georgia in mid-November flipped a would-be 38-37 loss into a 43-38 victory. (There is no similar outcome to Auburn's miraculous "Kick Six" victory over Alabama, and there probably never will be.)
Our FEI ratings actually favor Missouri in the SEC title game, so a final record of 12-2 like that of the 2011 Ducks is certainly in play. One common thread for Auburn in its closest calls this year has been losing the field-position battle. Auburn came up on the wrong side of field position against Mississippi State, Georgia and Alabama. Of course, all three of those games ultimately were won by the Tigers in dramatic fashion.
Alabama Crimson Tide (11-1)
Most similar profile: 2009 Florida (13-1)
There is a very remote possibility that Alabama can find itself back in the national championship game, but it certainly appears as if the Crimson Tide will be on the outside looking in. They have the potential to finish as one of the best teams ever to not play in a BCS title game, a distinction also held by the 2009 Florida Gators.
The '09 Gators ranked among the top 12 in all five of our measures in this similarity analysis, and Alabama does, as well. Both teams scored an average of 2.0 points per drive more than their opponents. Both teams produced scoring margin value from offense, defense and special teams. Alabama held opponents to seven or fewer points seven times this season, and the 2009 Gators did so six times.
If Alabama does settle for a non-championship BCS bowl, it will be interesting to see how the Crimson Tide handle that disappointment. Would this year's team dominate an inferior opponent the way the 2009 Gators did, posting a 51-24 victory over previously undefeated Cincinnati? Or will the 2013 Tide play more like the 2008 Alabama team that laid an egg against a motivated Utah team in the Sugar Bowl?
Missouri Tigers (11-1)
Most similar profile: 2010 Ohio State Buckeyes (12-1)
Missouri ranks fifth in the BCS standings this week, and the Buckeyes ranked sixth heading into the final weekend of the 2010 regular season. The key difference between the two situations is that Missouri has one more opportunity to post a victory and make a statement, whereas Ohio State had already wrapped up its regular season and could only watch the final weekend from the sideline.
The offenses were similarly productive and efficient. We measure value drives as possessions that move into scoring range by crossing the opponent's 30-yard line. Both 2013 Missouri and 2010 Ohio State earned value drives on at least 51 percent of their drives, and both scored an average of 5.4 points per value drive.
Missouri's challenge in the SEC title game will be slowing down
Nick Marshall and the potent Auburn offense, but it passed a big test this past weekend in limiting
Johnny Manziel's Texas A&M attack that ranks No. 1 nationally in opponent-adjusted offensive efficiency. Auburn keeps inventing more exciting ways to win, but, if Missouri plays as expected according to our data, Mizzou will win the SEC championship and hope one other domino falls ahead of it.
