No. 4 All-Time: Don Chaney
Chaney played for the Celtics in two separate stints, and literally bridged the eras between Bill Russell and Larry Bird. In his time with the franchise, he won two NBA championships in 1969 and 1974.
But, more than anything, his defensive chops made him such a valuable part of those teams. Chaney would be elected to five NBA All-Defensive Second Teams, four between 1972 and 1975, and another in 1977.
The Houston product averaged 8.7 points, 3.9 boards and 1.9 assists per game over 10 seasons with the Celtics.
