2015 NCAA Division I FBS football rankings

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

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.

This was the second season of the four-team College Football Playoff system which replaced the previous Bowl Championship Series system. At the conclusion of the regular season, on Sunday, December 6, 2015, the final CFP rankings will determine who will play in the two bowl games designated as semifinals for the 2016 College Football Playoff National Championship on January 11, 2016, at University of Phoenix Stadium in Phoenix, Arizona.
