The 2007 NCAA Division I FBS football season was the highest level of college football competition in the United States organized by the National Collegiate Athletic Association (NCAA).

The regular season began on August 30, 2007, and ended on December 1, 2007. The postseason concluded on January 7, 2008, with the BCS National Championship Game in New Orleans, where the No. 2-ranked Louisiana State Tigers defeated the No. 1 Ohio State Buckeyes to win their 2nd BCS and 3rd overall national title.

For just the second time in the Bowl Championship Series era, no FBS team finished the season undefeated. Kansas was the only team from a BCS automatic-qualifying conference to finish the entire season with just one loss.

Rules changes

After coaches expressed their disapproval of the timing changes made in the 2006 season, the following changes were made: On kickoffs, the clock will not start until the ball is touched in the field of play. On change of possession, the clock will not start until the snap. The attempt to reduce the time of games sought by those rules was successful, reducing the average college football page from 3:21 hours in 2005 to 3:07 hours in 2006. However, the reduced game time also reduced the average number of plays in a game by 13, 66 fewer offensive yards per game and average points per game by 5.

Other rules changes for the 2007 season include: Moving the kick-off yard-line from 35 to 30, which matches the yard-line used in the National Football League from 1994 to 2010, to reduce the number of touchbacks. Paring the 25-second play clock to 15 seconds after TV timeouts. Team time-outs for televised games are shortened from 60 seconds to 30 seconds. Allowing penalties against the kicking team on kickoffs to be assessed at the end of the runback, avoiding a re-kick, also matching the NFL rule. Once the umpire gives the ball to the kicker, the 25 second play clock starts. Kickoffs out of bounds are now penalized 35 yards from the spot of the kick or a re-kick with a five-yard penalty. Defenders cannot use any part of a teammate to jump over an opponent to block a kick.

Conference and program changes

The only change in conference membership for the 2007 season occurred when Temple left its Independent status to become the 13th member of the Mid-American Conference.

No teams upgraded from Division I FCS, leaving the number of Division I FBS schools fixed at 119.

Year of the Upset and "The Curse of No. 2"

Year of the Upset

The 2007 season was highlighted by the remarkable frequency with which ranked teams fell to lower-ranked or unranked opponents, leading the media to dub the season as the "Year of the Upset". An unranked or lower-ranked opponent defeated a higher-ranked team 59 times over the course of the regular season. Teams ranked in the top five of the AP Poll were defeated by unranked opponents 13 times during the regular season, setting a new record in the history of the AP Poll when at least 20 teams were ranked. The only other season to see more such upsets was 1967, which was one of seven seasons when the AP Poll ranked only 10 teams.

The chaos began on the first weekend of the season when FCS program Appalachian State defeated No. 5 Michigan on the road at Michigan Stadium in what was immediately hailed as one of the greatest upsets in the history of college football. Appalachian State became just the second FCS team to defeat a ranked FBS opponent, and the first to do so against a top-five team.
