2008 NAIA football rankings

One human poll made up the 2008 National Association of Intercollegiate Athletics (NAIA) football rankings, sometimes called the NAIA Coaches' Poll or the football ratings. Once the regular season was complete, the NAIA sponsored a 16-team playoff to determine the year's national champion. A final poll was then taken after completion of the 2008 NAIA Football National Championship.
