3. Dave Shula
A famous father can be a curse. The legendary Don Shula is one of the greatest NFL coaches in history. However, his son, Dave, went down as one of the worst. The Bengals hired the younger Shula in 1992. This was an exciting decision because of his pedigree. But it was a disastrous decision overall because Shula didn’t know what he was doing. Somehow, he survived for five seasons with a 19-52 record.

Finally, Cincinnati fired him in 1996 after a single win in seven games to start the season. Shula became the fastest coach in history to 50 losses during his time in charge (via USA Today). This was a uniquely bad achievement. It was a terrible time for the franchise because it was difficult for fans to maintain interest in the team. In the end, they lost patience and fired the younger Shula.
