Super Bowl
In the 2007 season, the Patriots became the fourth team in NFL history to have a perfect unbeaten and untied regular season record, the second in the Super Bowl era after the 1972 Miami Dolphins, and the first to finish 16–0. They easily marched through the AFC playoffs and were heavy favorites in Super Bowl XLII. However, they lost that game to Eli Manning and the New York Giants 17–14, leaving the Patriots' 2007 record at 18–1.
