Brady–Belichick era
The Tom Brady–Bill Belichick era, also known as the Brady–Belichick era, the New England Patriots dynasty, or the Patriots dynasty, was a sports dynasty of the New England Patriots in the National Football League (NFL) that lasted from the 2001 to the 2019 season. The dynasty is named after quarterback Tom Brady and head coach Bill Belichick, who are regarded as among the greatest in their respective positions. Belichick and Brady are consistently credited with the Patriots' success and are considered responsible for one of the sport's longest and most dominant dynasties. They are also credited with helping to create and sustain the culture around the team, dubbed the "Patriot Way", where there is an emphasis on personal accountability, consistent improvement, and a focus on team success over personal gain.
Under Belichick and Brady, the Patriots played in nine Super Bowls, more than any other NFL franchise, and won a league-record six (tied with the Pittsburgh Steelers). They also had 19 consecutive winning seasons, 17 division titles (including 11 consecutive from 2009 to 2019), 13 AFC Championship Game appearances (including eight consecutive from 2011 to 2018), and the only undefeated 16-game regular season in 2007. The Patriots appeared in half of all Super Bowls played during Brady's 18 seasons as the primary starter and won two-thirds of those they played in.
In addition to helping set the Patriots' franchise records, Brady and Belichick hold the records for the most Super Bowl appearances and victories by a player and head coach, respectively. Belichick also holds the records for the most playoff wins by a head coach (31) and Super Bowl appearances by an individual (12), while Brady holds the quarterback records for career wins (264), regular season wins (230), and playoff wins (34) and the record for Super Bowl MVP awards (five).
The era came to an end when Brady left the Patriots as a free agent for the Tampa Bay Buccaneers in March 2020. Belichick remained as head coach until January 2024.
