FPI favors Pac-12, ACC in power rankings

11/11/2013

The SEC continues to lead ESPN Stats & Info’s Conference Power Rankings by a wide margin after an exciting slate of games in Week 11.

As noted in previous posts, the Conference Power Rankings are a formula that equally weighs the rankings from the AP Poll and ESPN’s new Football Power Index (FPI) in order to determine the best and worst conferences in the country.

The idea is that the AP Poll measures a team’s résumé and perception, and the FPI measures a team’s relative strength in order to predict future success. In other words, the AP Poll answers the question, “If there were a playoff, who would deserve to play in it?” and the FPI answers, “If there were a playoff, who would win on a neutral field?”.

How do these compare in terms of conference strength?

The SEC has seven teams ranked in the top 25 of the AP poll, including four teams ranked in the AP top 10. No other conference has more than four total teams ranked in the AP top 25.

In comparison, the Pac-12 leads all conferences with seven teams in the top 25 of the FPI. The SEC is second with six teams, but only one of those teams – Alabama – ranks in the top 8. The Pac-12 has four teams in the top 8.

It is important to note that the SEC has two more teams than the Pac-12, which makes the Pac-12’s lead in the FPI even more impressive.

This is not an indictment of the SEC; the conference had the most teams ranked in the FPI top 25 last season. However, this season, the SEC does not have as many elite teams as in past years. According to FPI, the majority of their teams rank in the 20 to 40 range.

The Pac-12 actually has the most depth at the top of its conference. When Stanford loses to a team like Utah, who has played the hardest schedule thus far according to ESPN strength of schedule rankings, it may not be as much of an upset as many would expect.

FPI also favors the ACC more than the polls. Florida State is the top team in the FPI, and Georgia Tech, Clemson, Miami and Duke also rank in the top 25.

In the annual ACC vs. SEC matchups at the end of the season, FPI projections favor Florida State over Florida, Georgia Tech over Georgia and Clemson over South Carolina.

So, while the SEC is getting all the accolades in the polls, future performance may be on the side of their rival conferences. The good news is that this debate will be settled on the field. Keep an eye on the FPI as bowls approach in order to determine the relative strength of teams and conferences.
