The New York Knickerbockers, more commonly referred to as the Knicks, are an American professional basketball team based in the borough of Manhattan, in New York City. The Knicks compete in the National Basketball Association as a member of the Atlantic Division of the Eastern Conference. The team plays its home games at Madison Square Garden, an arena they share with the New York Rangers of the National Hockey League. They are one of two NBA teams located in New York City; the other is the Brooklyn Nets. Alongside the Boston Celtics, the Knicks are one of two original NBA teams still located in its original city. The team, established by Ned Irish in 1946, was one of the founding members of the Basketball Association of America, which became the NBA after merging with the rival National Basketball League in 1949. The Knicks were successful during their early years and were constant playoff contenders under the franchise's first head coach Joe Lapchick. Beginning in 1950, the Knicks made three consecutive appearances in the NBA Finals, all of which were losing efforts. Lapchick resigned in 1956 and the team subsequently began to falter.
