Every player in Boston Celtics history who wore No. 12

Today’s installment focuses on the 34 players who wore No. 12 over the years as of September 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 played in them, their unretired jersey numbers pack in some of the most history not hanging from the rafters of any team in the league.

Today’s installment focuses on the 34 players who wore No. 12 over the years as of September 2023.

On this day: Reggie Lewis dies; Brown, Rozier, Green, Crowder signed

On this day, former Celtics forward Reggie Lewis died unexpectedly while working out due to a heart arrhythmia.
