Boston Celtics

Founded in 1946 and one of eight NBA teams (out of 23 total teams) to survive the league's first decade

From 1957 to 1969, the Celtics dominated the league, winning eleven championships in thirteen years and eight in a row (1959–1966), the longest consecutive streak of any North American professional sports team. The Celtics dominated the league during the late 1950s and through the mid-1980s, with the help of many Hall of Famers which include Bill RussellBob CousyJohn HavlicekLarry Bird and legendary Celtics coach Red Auerbach, combined for a 795–397 record that helped the Celtics win sixteen Championships. Before the retirement of the “Big Three”, who included Larry BirdRobert Parish and Kevin McHale, thanks to some creative maneuvering by Auerbach, the Celtics had drafted second overall pickLen Bias but the team fell into decline as the college star died two days after he was drafted. Later, the team suffered another tragedy when their star player Reggie Lewis died of a heart attack in his prime.[2]
