The Boston Celtics' jersey history reflects a rich legacy, featuring 68 different numbers worn by over 500 players. The No. 13 jersey, notably worn by Tristan Thompson during the 2020-21 season, represents a significant chapter in this narrative. Drafted fourth overall by the Cleveland Cavaliers in 2011, Thompson played nine seasons with the Cavs before joining the Celtics. During his brief tenure in Boston, he averaged 7.6 points, 8.1 rebounds, and 1.2 assists per game before being traded to the Sacramento Kings.
