While the New York Knicks have been considered one of the worst teams in the NBA at various points in time, they were actually considered to be one of the best during the 1995-1996 season, which was when Eddie (1996) was first released into theaters. Although the movie portrayed them to be the worst, the real life Knicks had just appeared in the NBA Finals 2 years prior to the films release in 1994, losing to the Houston Rockets. As of 2023, the Knicks have not made it to the NBA Finals since 1999, and have not won since 1973.
