Every player in Boston Celtics history who wore No. 21

Today’s installment focuses on the nine players who wore No. 21 over the years as of August 2023.

The Boston Celtics have more retired jerseys than any other team in the NBA, but that doesn’t mean the rest of their jerseys have little history of interest tied to them.

In fact, with 17 titles to their name and decades of competitive basketball, their unretired jersey numbers pack some of the most history not hanging from the rafters of any team in the league. To that end, we have launched our accounting of that history with every player in every jersey worn by more than one Celtics player in the storied franchise’s history accounted for.

Today’s installment focuses on the nine players who wore No. 21 over the years as of August 2023.

On this day: Kelly Olynyk, Gabe Pruitt, Jack Foley born; ‘Celtic Pride’ debuts

On this day, Kelly Olynyk, Gabe Pruitt, and Jack Foley were born, and the film ‘Celtic Pride’ came out.

On this day in Boston Celtics history, big man and future Celtic Kelly Olynyk would be born in Toronto, Ontario, Canada in 1991, later moving west to Kamloops, British Columbia when he was in seventh grade.

Olynyk played his college ball at Gonzaga and was drafted by the Dallas Mavericks with the 13th overall pick in the 2013 NBA draft before being immediately dealt to the Celtics. Olynyk would make the 2013-14 All-Rookie team and would play for Boston for four seasons over which he averaged 9.5 points, 4.7 rebounds, and 1.7 assists.

The Canadian big man would leave the Celtics in free agency for the Miami Heat in the summer of 2017.
