Bill Belichick has been the most successful NFL coach of the 21st century and his six Super Bowl wins are the most all-time. Since 2001, his second year as New England Patriots’ coach, Belichick has posted a remarkable 18 consecutive winning seasons, appeared in nine Super Bowls, and advanced to eight straight conference championship games. While perceived as grumpy and mysterious, Belichick is renowned as a master tactician and a genius in strategy. Analysts, players, and fellow coaches praise and marvel at his encyclopedic knowledge of the X’s and O’s, his unusual attention to detail, and the meticulousness and wisdom of his preparation. Before taking over in New England, Belichick was the Giants’ defensive coordinator from 1985-1990, during which time he won two Super Bowls, and was the Browns’ head coach from 1991 to 1995. Belichick ranks third all-time in coaching wins, trailing only George Halas and Don Shula.
