The 2009 season was the New England Patriots' 40th in the National Football League (NFL), their 50th overall and their 10th under head coach Bill Belichick. They finished with a 10–6 record and a division title before losing to the Baltimore Ravens in the playoffs.
This was the first of eleven consecutive AFC East titles for the Patriots. After missing the playoffs in 2008, the Patriots' offseason was marked by a number of front office, coaching, and personnel changes. Vice President of Player Personnel Scott Pioli, who had been head coach Bill Belichick's personnel director since 2000, departed to become the general manager of the Kansas City Chiefs, while offensive coordinator Josh McDaniels was named head coach of the Denver Broncos. Quarterback Matt Cassel, who led the team to 11 wins in 2008 after starter Tom Brady was injured, was traded to the Chiefs along with veteran linebacker Mike Vrabel in March. Defensive starters Tedy Bruschi and Rodney Harrison both retired, while All-Pro defensive end Richard Seymour was traded to the Oakland Raiders for a first round pick in the 2011 NFL draft days before the start of the regular season.
In the season opener on Monday Night Football, the Patriots celebrated their 50th anniversary season with an American Football League "legacy game" against the Buffalo Bills. Down 11 points late in the fourth quarter, the Patriots would score two touchdowns to secure a victory in Brady's first game back from injury. In November, the 6–2 Patriots traveled to face the undefeated Indianapolis Colts; with a six-point lead late in the fourth quarter, the Patriots tried to convert a 4th and 2 situation inside their own 30-yard line but failed, setting up a Colts touchdown and the Patriots' third loss of the season. After losing another two games of three, the Patriots went on to win their next three games to secure a division title; the team also finished with their fourth perfect regular season record at home in seven years. With the third seed in the AFC playoffs, the Patriots faced the Baltimore Ravens at home in the Wild Card Playoffs. The Ravens opened a 24–0 lead in the first quarter and the Patriots could not recover, ending their season, the Pats suffered their first one-and-done postseason campaign since 1998 and the first in the Brady-Belichick era.
