An assistant with the Giants
Belichick began a 12-year tenure with the New York Giants in 1979. He won his first two Super Bowls as a defensive coordinator for Bill Parcells. Belichick headed one of the most dominant groups of linebackers in NFL history, which included Hall of Famers Lawrence Taylor and Harry Carson. The magical seasons came in 1986 and 1990, giving him the credentials he needed to make the leap to head coach in the NFL.
