The 2008 NFL season was the 89th regular season of the National Football League (NFL), themed with the slogan "Believe in Now."

Super Bowl XLIII, the league's championship game, was at Raymond James Stadium in Tampa, Florida, on February 1, 2009, with the Pittsburgh Steelers coming out victorious over the Arizona Cardinals and winning their NFL-record sixth Vince Lombardi Trophy.

Conversely, the Detroit Lions became the first NFL team with a winless season since the strike-shortened 1982 NFL season, finishing their season 0–16. For the first time since the NFL expanded to the sixteen-game season in 1978, three teams won two or fewer games: the Lions, the Kansas City Chiefs, and the St. Louis Rams. Previously two teams won two or fewer games in 1979, 1981, 1983, 1985, 1992, and 2001. Also, for the first time since the 1985 Denver Broncos, a team finishing with an 11–5 record missed the playoffs- the defending AFC champion New England Patriots. Also, for the first time, two divisions (the NFC East and the NFC South) had no team finish with a losing record.

Draft

The 2008 NFL Draft was held from April 26 to 27, 2008 at New York City's Radio City Music Hall. With the first pick, the Miami Dolphins selected offensive tackle Jake Long from the University of Michigan.

New referees

Gerald Austin and Larry Nemmers retired. Carl Cheffers and Alberto Riveron were promoted to referee. Ron Blum also retired from line judge position.

Rule changes

The following rule changes were passed at the league's annual owners' meeting in Palm Beach, Florida, during the week of March 31: One defensive player will be allowed to wear a radio similar to the one worn by the quarterback to communicate with the coaching staff on the field. The "force-out" rule on catches made near the sidelines has been eliminated. A receiver now must come down with the ball and both feet in bounds for a pass to be ruled complete; previously, passes would be ruled complete if the receiver was pushed by a defender while in the air and the official judged that he would have come down in bounds had he not been pushed. However, if a receiver is wrapped up in mid-air by a defender and carried out of bounds before both feet touch the ground, the official can still rule the play a completion. The 5-yard incidental grabbing of the face mask penalty has been eliminated; incidental contact will not result in a penalty, though intentional grabbing of the face mask will remain a 15-yard personal foul. Teams that win the opening coin toss now have the option to defer the decision until the start of the second half, the same as in college and Canadian football. Field goal attempts that bounce off the goal post are now reviewable under instant replay. Legal forward hand offs that touch the ground and attempted snaps when the ball hits the ground before the quarterback touches it are now considered fumbles; previously, forward hand offs were treated as incomplete passes, while a snap that hit the ground before the quarterback touched it was a 5-yard illegal procedure penalty.

Preseason

In preseason games, the annual Pro Football Hall of Fame Game was played August 3 between the Indianapolis Colts and Washington Redskins, which aired on NBC. Washington won the game, 30–16. Other preseason highlights included the first game of the Toronto Series, which was played August 14 between the Buffalo Bills and the Pittsburgh Steelers at Toronto's Rogers Centre. The Bills won that game, 24–21.

Opening Weekend

The annual NFL Kickoff Game to start the season took place on September 4 and featured the Super Bowl XLII champion New York Giants winning over their division rivals, the Washington Redskins, at Giants Stadium by a score of 16–7. The game's kickoff was ninety minutes earlier than previous years, at 7 p.m. EDT, because of a time conflict with the 2008 Republican National Convention.
