New York fans rejoiced after the Knicks acquired hometown hero Stephon Marbury, but he quickly became a villain in New York as the Knicks made the playoffs once (swept in first round of '04) throughout his tenure in New York. It was a disappointing stretch that saw Marbury cause more harm than good. That harm includes the Anucha Brown Saunders scandal as well as fights with coaches Larry Brown and Mike D'Antoni.
