8. Bill Hanzlik
Hanzlik’s tenure is one of the shortest on this list. A decent player, he spent most of his career with the Denver Nuggets. Then he decided to take the step into coaching. After serving as an assistant in Charlotte and then with Atlanta, he replaced Dick Motta as head coach of the Denver Nuggets.

This turned out to be a disastrous decision. His overall record was 11-71, which is frankly grim reading. The Nuggets’ longest winning streak during this miserable season was two games. In contrast, they had losing streaks of 12, 16, and 23. This entry belongs in infamy.
