Dick LeBeau and the Pittsburgh Steelers have agreed to part ways.

LeBeau is considered one of the best defensive coordinators of all-time and the creator of the zone blitz.

LeBeau had been the Steelers defensive coordinator since 2004, working under Mike Tomlin since 2007.

LeBeau told the Urbana (Ohio) Daily that he was stepping down and not retiring. LeBeau is currently 77 years old.
