Belichick began his coaching career in 1975 and became the defensive coordinator for New York Giants head coach Bill Parcells by 1985. Parcells and Belichick won two Super Bowls together before Belichick left to become the head coach of the Cleveland Browns in 1991. He remained in Cleveland for five seasons but was fired following the team's 1995 season. He then rejoined Parcells, first in New England, where the team lost Super Bowl XXXI, and later with the New York Jets.
