IMO, the best team of all time is the 1986 Celtics.
DJ
Ainge
Bird
McHale
Parish
How could any team beat a frontline that per game put up:
63.2 points, 27.4 rebounds and 4.0 blocks on 53.2 percent shooting
You had 4 guys who averaged over 15 points per game.
The 6th man gave you 14.1 points, 12.7 rebounds and 2.5 blocks per 36 minutes on 56.2 percent shooting (Walton).
DJ and Ainge were a great combination in the backcourt. DJ could D up, Ainge was a very good knockdown shooter.
Nobody will ever top the 86' Celtics.
