13. Stu Jackson
Jackson’s time with the Knicks was an absolute shambles. To be fair, the Knicks and shambles are two words that often go together. But this was a particularly bleak time in the New York franchise’s history. When he took over they were actually decent and coming off of a playoff appearance.

The expectation was that they would at least match that, if not go on to win the title. But instead, he blunted their attack, turning them from a fast team to a half-court team. After going 7-8 in his second season, the Knicks fired him. They went on to make 10 straight playoff appearances without him.
