10. Stu Jackson

Team(s): New York Knicks & Vancouver Grizzlies
Tenure: 1989-1991/ 1996-1997
Overall Record: 58-78

When Stu Jackson took over the Knicks, they were coming off a first place season, a semifinal playoff run and were loaded with talented players like Patrick Ewing, Mark Jackson and Charles Oakley. Jackson's first order of business was to overhaul the offense; turning the running Knicks into a half court team was a big mistake. The Knicks got worse, falling to third place in the Atlantic Division in Jackson's first season. When the team started 7-8 in '90-'91, Jackson was fired. With Jackson an afterthought, the Knicks started the '91-'92 season behind Pat Riley and would go on to make ten straight playoff appearances.
