Bill Belichick confirmed on Thursday that he is leaving the New England Patriots after 24 seasons and six Super Bowl titles.

The departure brings to an end one of the greatest head-coaching runs in NFL history, during which time Belichick changed the fortunes of the Patriots organization.

Paired with era-defining quarterback Tom Brady, Belichick transformed the Patriots into one of the league's juggernauts, almost consistently making deep playoff runs and contending for the Vince Lombardi Trophy. But following Brady's departure to the Tampa Bay Buccaneers in 2019, the team has struggled in the regular season and playoffs, with New England finishing with a 4-13 record this past season.

Belichick is the only head coach in NFL history to win six Super Bowl titles. He ranks second all-time with 333 total victories as a head coach. His 31 career playoff wins are the most all-time among head coaches.

Belichick later became Parcells' defensive coordinator, and they won two Super Bowl titles together. Parcells acted as a mentor for a young Belichick, and their relationship was later immortalized in an ESPN special, "The Two Bills."
