2. Cousy and Russell
Seasons Played Together: 7 (1956-1963)
NBA Titles: 6
Bob Cousy and Bill Russell will forever be the greatest tandem in Celtics history. Bill led the defensive end while Cousy quarterbacked the offensive side of the ball. Under Red Auerbach, these two, along with legends like K.C. Jones and Hondo, revolutionized the game of basketball for generations to come. Cousy was a wizard with the ball and Russell turned shot-blocking into an art form. The Celtics changed the game by implementing the role of the sixth man and breaking color barriers.
