From NYTimes.com: After the Zone Blitz, the Deadpan Defense
In between extremely successful stints as the Pittsburgh Steelers defensive coordinator, Dick LeBeau was first defensive coordinator and later head coach of the Cincinnati Bengals. It was three seasons of total futility, even with the Bengals defenses running the same zone blitz schemes that worked so well for the Steelers. Probably more an indictment of the Bengals personnel department or lack thereof rather than Dick LeBeau’s coaching ability. Sometimes, though it seems that certain coaches are more suited to being a defensive or offensive coordinator and not a head coach.
