8. Marty Mornhinweg
Mornhinweg lasted two seasons in charge of the hapless Detroit Lions. They went 2-14 in their first year under his leadership and 3-13 in the second. This should provide an indication of how terrible he was in the hot seat. Furthermore, he was directly responsible for some of their losses. One clear and notorious example occurred at the end of a game against the Chicago Bears.

Mornhinweg won the overtime coin toss and chose the direction to defend instead of the ball. Of course, everybody knows that taking the ball is almost always the right course of action. However, Mornhinweg pointed to the wind direction, placing more value on that than possession. It was almost poetic that the Bears won the game by way of a 40-yard field goal.
