17. 1972-73 Boston Celtics
On paper, this is one of the best versions of the Celtics we’ve ever seen. They set a number of franchise records but fell short of winning the grand prize. Despite this, their 68-14 record is still the best in franchise history. Unfortunately, they couldn’t carry that into the postseason.

In the Eastern Conference Finals, the Celtics lost to the Knicks. But it was still an outstanding season with numerous players picking up individual awards. The NBA named Dave Cowen the NBA MVP ahead of Kareem Abdul-Jabbar and Tiny Archibald.
