The Boston Celtics have won 17 NBA Championships, more than any other team. This includes 11-of-13 from 1957-1969 and eight in a row starting in 1958, a North American record for consecutive professional championships.
The Celtics have posted a winning record in 48 of 62 seasons. They had 27 non losing win/loss records in succession from 1950-1976.
Traditionally, the Celtics have always had a big three.
In the 1960s: Cousy, Jones, and Russell.
In the 1970s: Cowens, Havlicek, and White.
In the 1980s: Bird, McHale, and Parrish.
Starting in 1993, Boston posted losing records in eight consecutive seasons, putting them in an unfamiliar position—a team without a chance.
In recent years, the rise of a new big three has brought hope back to Beantown, with Paul Pierce, Kevin Garnett, and Ray Allen.
This list recognizes the top 50 players in Celtics history. I based the list on the "Win Share" statistic available through http://www.basketball-reference.com/.
I only counted statistics for players while with the team (regular season and playoffs).
