4. Stephon Marbury
The Knicks gave up five players and two first-round picks to acquire Marbury and an aging Anfernee Hardaway in 2004. It was a homecoming for the Brooklyn native and fans were instantly excited only to suffer immense disappointment. Starbury played four and half seasons with the Knicks, and the team had just one playoff appearance to show for it.
His time in New York is better remembered for off-court feuding with Knicks coaches and front-office members than his on-court play. Marbury averaged 21.7 points per game in his first full season in the Big Apple, but his production steadily declined.
At the start of the 2008-09 season, Marbury lost his starting point guard job to Chris Duhon. The 31-year-old guard refused to play and was suspended by the team until being released in February 2009.
Marbury played just 23 more NBA games with the Boston Celtics before finishing his career in China. It was a disastrous tenure that the New York Knicks should have ended long before they did. In his four full seasons with the franchise, they won just 111 games and were dysfunctional both on and off the court.
The Stephon Marbury era was a massive bust that led to a six-year playoff drought, and it is a time Knicks fans would prefer to forget about.
