4. Dave Shula
Shula was ludicrously out of his depth as head coach of the Bengals. The most shocking thing is that they let it go on for so long. He lasted for just over three seasons in Cincinnati, but it was a time of true despair and suffering for the Bengals faithful. ‘The Bungles’ era was bad even by the Bengals’ lowly standards.

First of all, Shula’s own players didn’t take him seriously. That should have been a warning sign. He went 19-42 from 1992 to 1996. Finally, they fired him just seven games into his fourth season. They were at 1-6. He still gives older fans nightmares. The owners also deserve criticism for letting him go on for so long.
