Cincinnati Bengals
Marvin Lewis coached the Bengals for 16 seasons but never won a playoff game. He made the franchise respectable but didn’t do anything spectacular with them. The fanbase appreciates his loyalty but there’s no denying that everything went stale in the end. But the same can’t be said about Zac Taylor (via Fansided).

Nobody expected him to be Cincinnati’s best coach of the past two decades after a 2-14 rookie coaching season. But then they seized Joe Burrow with the first overall pick in 2020. This changed the franchise’s fortunes and they played in a Super Bowl two seasons later. They didn’t win but remained in contention as Taylor built an electrifying offense.
