Honorable mention, part I
Dwayne Schintzius – 1999
Schintzius was with Boston for just one season at the end of the last millennium, perhaps better known for his haircut — a mullet — than his game.
Mostly, this was due to injury, and he would be done with the NBA after his 16-game stint with the Celtics, with whom he averaged 0.7 points, 1.2 rebounds and 0.5 assists.
Jordan Mickey – 2016-2017
A popular draft pick taken 33rd overall by Boston in the 2015 NBA Draft, Mickey never put it together while with the Celtics, averaging 1.4 points, 1.1 rebounds and 0.2 assists in his two seasons with the team.
He now plays in Europe with Real Madrid after stints with the Miami Heat and Khimki, a Russian team based in Moscow.
Luke Harangody – 2011
Harongody wasn’t exactly a Celtics lifer either. But he was a solid rotation big for a hot second with Boston, logging 2.3 points, 2 rebounds and 0.4 assists over 23 games in the 2010-11 NBA season after having been taken 52nd overall in the preceding draft.
He would be traded to the Cleveland Cavaliers that same season along with Semih Erden for a second-round pick.
