The Boston Celtics are a professional basketball team based in Boston, Massachusetts. They play in the Atlantic Division of the Eastern Conference in the National Basketball Association (NBA). Founded in 1946, the team is currently owned by Boston Basketball Partners L.L.C. and coached by Doc Rivers, with Danny Ainge as the President of Basketball Operations. The Celtics' 17 NBA Championships are the most for any NBA franchise. The Celtics' greatest domination came from 1957 to 1969, with 11 championships in 13 years, and eight in a row (1959–1966), the longest consecutive championship winning streak of any North American professional sports team. They currently play their home games at TD Garden.
The Celtics either dominated the league or played a large part in the playoffs in the late 1950s through the mid 1980s (winning 16 NBA Championships in 30 years between 1957 and 1986, and reaching at least the conference championship series in 29 of 35 seasons between 1953 and 1988). After the deaths of the second overall draft pick Len Bias in 1986 and all-star Reggie Lewis in 1993, the team fell into a steady decline, only making the playoffs four times from 1996 to 2007. The franchise has recently returned to prominence when Kevin Garnett and Ray Allen joined Paul Pierce during the 2007 off-season. Four Celtics (Bob Cousy, Bill Russell, Dave Cowens, and Larry Bird) have won the NBA Most Valuable Player Award for an NBA record total of 10 MVP awards.
