The Boston Celtics have a storied history with 68 different jersey numbers worn by over 500 players since their inception. Among these is the No. 20 jersey worn by Wayne Kreklow during the 1980-81 season. Drafted 53rd overall by the Celtics after his college career at Drake, Kreklow played only one season in the NBA, contributing as a deep reserve on a championship team. He retired after that season, averaging 1.2 points per game. The Celtics have retired 25 jerseys in honor of their greatest players, making the history of each number significant.
