Kenneth Massey maintains a comparison of all the major college football rankings and rating systems. They are aggregated to provide a consensus ranking of all 120 teams at the FBS level.Additionally, each team's high ranking, low ranking, mean ranking, median ranking, and standard deviation are provided. For each individual ranking system included in the comparison, the correlation to consensus (i.e. how much the rankings agree with everyone else) and the ranking violation (i.e. how many times did the lower ranked team win) are provided.
The ranking comparison includes rankings that result from:
- A human poll conducted by a major publication or group (e.g. the AP)
- An advanced computer rating.
- A mathematically based sequential rating (e.g. Elo's update formula)
- Publicly well-known systems (e.g. the RPI)
The Rogers Poll is the only system that ranks Nebraska #1 and has the consensus #1, Alabama, rated lower than anyone else (#9). The correlation to consensus among the Top 25 is low, but the correlation to consensus for all 120 teams is high.
The final rankings of the college basketball season painted a similar story. The correlation to consensus for the Rogers Poll among all teams was high, but the correlation to consensus among the Top 25 was low (35th of 37 rankings). However, the ranking violation (i.e. accuracy) of the Rogers Poll among the Top 25 was the best!
What does it mean? For the most part, all the major systems have a rough correlation to one another with regards to ranking every team from top to bottom. However, there can be significant disagreement among the top teams (where the most interest is). In this case, do not look for who most agrees with everyone else when you can look for who is the most accurate.
Last year, the Rogers Poll had eventual national champion and consensus #1 Alabama ranked higher than any other system in the preseason rankings (#4 in Rogers Poll, #7 consensus among 44 others).

Joe Kasulis maintains the CFL prediction tracker that documents the accuracy of 12 participating models with regards to picking straight up winners, picking against the spread, and accurately predicting game scores.
The preseason Rogers Poll for the 2010 college football season has been released. A surprise to many, Nebraska appears in the #1 spot. The Huskers are coming off a 10-win season that included a narrow loss to 2009 runner-up Texas in the Big XII Championship game and a blowout/shutout win over a good Arizona team in the Holiday Bowl.
