When Bill Russell retired in 1969, the Boston Celtics really bottomed out - for a year.
In 1970 and 1971, the Celtics missed the playoffs for the first time since 1950.
But wily Red Auerbach picked Dave Cowens in the 1970 draft, partly at Russell’s recommendation, and the rebuild was underway. Cowens was smallish at center even in the 1970s. Just 6-9 and 230, and with relatively short arms, he compensated with immense intensity and energy.
Cowens teamed with the late John Havlicek, the key holdover from Boston’s astounding dominance in the late 1950s and 1960s, to bring Boston right back to the forefront.
