5. Dick LeBeau
LeBeau was a magnificent defensive coordinator before he retired in 2017. He had 59 seasons in the NFL with franchises like the Titans and the Steelers. But he only had a single head coach role and it was disastrous. He never stepped up to the position again because it didn’t suit his talents. LeBeau took over in Cincinnati in 2000 but lost his job following the 2002 year.

The franchise failed to progress during his tenure. He posted three losing seasons and lost his job after the Bengals finished 2-14. Unfortunately, the legendary coach helped the franchise to their worst record in history. Meanwhile, he had a miserable winning percentage of just .267 (via ESPN). Luckily, LeBeau had enough credit in the bank to bounce back and rebuild his career.
