ESPN unveiled the first trailer for its latest documentary in its “30 for 30” TV series this week entitled “The Two Bills”, which focuses on the relationship between coaching legends Bill Parcells and Bill Belichick over the course of their NFL careers working together and apart.
Before being an accomplished head coach in New England, Belichick gained most of his coaching experience from Parcells while working under him as a assistant coach and defensive coordinator with the Giants (1979-1990), defensive backs coach with the Patriots (1996) and Jets defensive coordinator (1997-1999). Belichick won his first two Super Bowl rings with Parcells and the Giants in 1986 and 1990.
