15. Dave Shula
Don Shula is the winningest coach in NFL history. The Cincinnati Bengals thought that success was genetic, however, that proved not to be the case. They found this out the hard way after hiring Don’s son Dave. He proceeded to run the franchise into the ground during some of the darkest days in its history. It can take a generation for a team to recover from that kind of mismanagement.

Shula became the fastest NFL coach in history to drop 50 games. Furthermore, he wasted draft picks like they were lottery tickets over his five years in charge. His overall record was 19-52, including two losses to his father. After a torturous 1-6 run in 1996, the Bengals finally fired him. Why’d it take so long?
