The NCAA Division I-FBS National Football Championship is an annual designation awarded by various third-party organizations to their selection(s) of that season's best college football team(s) in the National Collegiate Athletic Association's Division I–Football Bowl Subdivision. Division I-FBS football is currently the only NCAA sport that is not decided by a playoff or tournament based system. Due to the fact that the championship team is not decided by a playoff or tournament based system, it is often unofficially referred to as a Mythical National Championship[1][2][3]. This is a highly controversial "Championship" since the NCAA does not officially declare a national champion for the Division I-FBS. The championship team is independently declared by many separate individuals and organizations, often referred to as "selectors".[4] These choices are often at odds with each other. Currently, the most recognized organizations selecting national champions are the Associated Press, which conducts a poll of football sportswriters, and the USAToday Coaches' Poll, a poll of American Football Coaches Association active coaches that is contractually obligated to name the winner of the Bowl Championship Series championship game as its national champion.   «   Summary from Wikipedia
