4. Bill Belichick (1994-current) began his coaching career in 1975, and by 1985, he was the Defensive Coordinator for New York Giants head coach, Bill Parcells. Parcells and Belichick won two Super Bowls together (XXI and XXV), before Belichick left to become the head coach in Cleveland in 1991. He remained in Cleveland for five seasons, and was fired following the team's 1995 season. Belichick then rejoined Parcells, first in New England where the team lost Super Bowl XXXI, and later with the New York Jets. After being named head coach of the Jets in early 2000, Belichick resigned after only one day on the job to accept the head coaching job for the New England Patriots. Belichick has led the Patriots to 14 AFC East division titles and 11 appearances in the AFC Championship Game. He was named the AP NFL Coach of the Year for the 2003, 2007, and 2010 seasons. Since then, he has coached the Patriots to seven Super Bowl appearances. His teams won Super Bowls XXXVI, XXXVIII, XXXIX, XLIX, and LI. Belichick's appearance in Super Bowl LI broke the tie of six Super Bowls as a head coach that was shared with Don Shula, as well as being a record tenth participation in a Super Bowl in any capacity, overtaking the tie of nine that he shared with Dan Reeves. This also tied him with Neal Dahlen for the most Super Bowl wins in any capacity with seven. In addition, the appearance in Super Bowl LI was the Patriots' ninth Super Bowl appearance in franchise history, which is the most of any team. Belichick is the NFL's longest-tenured active head coach, and currently ranks fourth all-time in regular season coaching wins in the NFL at 237, and first in playoff coaching wins with 26. He completed his 40th season as an NFL coach in 2014 and won his fifth Super Bowl as a head coach following the 2016 season, surpassing former Pittsburgh Steelers head coach Chuck Noll as the only head coach to win five Super Bowls. He is one of only five head coaches with four or more titles in NFL histor
