Imagine trying to be the replacement for Bill Russell. Undersized but undeterred, Cowens stepped up fearlessly to that impossible task, averaging 17 points and 15 boards as a rookie.
Cowens averaged a crazy 17 points and 13 rebounds for his career and was a key clog in two more NBA titles for the Boston Celtics. Without him those would not have been achieved.
Cowens made 8 All-Star Teams, 3 All NBA Defensive Teams, won an MVP award and made two All-NBA teams. Not a bad replacement.
