Dick LeBeau has either coached or played in the NFL for 59 straight years. He was drafted by the Browns when Jim Brown still roamed the backfield and made a career of playing defensive back against the likes of Johnny Unitas. After retiring in 1972, he immediately moved into a coaching role, popularizing the zone blitz for the Bengals in the 1980s. He wasn't successful as a head coach in Cincinnati during the early 2000s, but coached the Steelers' defense to two Super Bowl titles and was inducted into the Hall of Fame in 2010.
