2015_NCAA_Division_I_FBS_football_rankings
Two human polls and a committee's selections comprised the 2015 National Collegiate Athletic Association (NCAA) Division I Football Bowl Subdivision (FBS) football rankings, in addition to various publications' preseason polls. Unlike most sports, college football's governing body, the NCAA, does not bestow a national championship, instead that title is bestowed by one or more different polling agencies. There are two main weekly polls that begin in the preseason—the AP Poll and the Coaches Poll. One additional poll is released midway through the season; the College Football Playoff (CFP) rankings are released after the eighth week.
