Championships - 3 (1981, 84, 86)

The 1986 Boston Celtics are in the conversion for one of the greatest single-season teams of all-time. That combined with the franchise's dominance in the early 1980's pretty much sealed the team's spot on this list. They relied on the superstar duo of Larry Bird and Kevin McHale but even without them, the team had one of the best supporting casts ever in Robert Parish, Danny Ainge, Dennis Johnson, Cedric Maxwell and Bill Walton (1985-87).

They battled a tough Eastern Conference in the early 1980's and reached the Finals five times in seven years including four straight from 1984 to 1987. For three straight years from 1984-86, the MVP Award (Bird) and Sixth Man of the Year Award (Kevin McHale twice and Bill Walton once) belonged to the Celtics.

Now, why are the 5th?

Only three championships and a dynasty that lasted seven years. Nothing wrong with that except the fact that teams higher on this list have achieved and won more over a slightly longer period of time.
