Coach Ime Udoka knew his players and set very well. This was the team that resembled a winning team the most. They led the league in least points allowed per game and were second in defensive rating. The Jayson Tatum, Jaylen Brown, and Marcus Smart core had hit their peak. Unfortunately, they conceded the title to Stephen Curry’s Golden State Warriors.

10.  1966-67 Boston Celtics (60-21 record)

Bill Russell as a playing coach was something else. His team led the league in defensive rating. They were also a top-four offense in the NBA. However, fatigue caught up to them as they lost to the Sixers in five games.
