Here is a comprehensive summary of the 2007 NFL season:

The 2007 NFL season, the league's 88th, ran from September 6 to December 30, kicking off with the defending champion Indianapolis Colts defeating the New Orleans Saints in the Kickoff Game. The campaign's biggest storyline was the New England Patriots becoming the first team to finish the regular season undefeated since the 16-game schedule began in 1978, only to have their perfect-season bid shattered by a 17–14 loss to the New York Giants in Super Bowl XLII on February 3, 2008. Notably, it was the first year that two divisions (the NFC East and AFC South) finished with no losing records, and the draft saw the Oakland Raiders select quarterback JaMarcus Russell with the first overall pick. Significant rule changes that year made the instant replay system a permanent officiating tool (upgraded to high-definition) and altered catch and touchdown definitions, while official John Parry was promoted to referee after Bill Vinovich resigned due to a heart condition. The season also marked the retirement of numerous stars, including Marshall Faulk, Curtis Martin, Drew Bledsoe, and Tiki Barber, and the preseason opened with the Hall of Fame Game in Canton.
