Even for the Boston Celtics’ storied past, what head coach Joe Mazzulla has achieved in his young career is already pretty good, and now it has awarded him with a multi-year contract extension, which it announced on Friday.
In three seasons, Mazzulla has won an NBA championship and owned the best record in the league during that span. The Celtics have won the Atlantic Division every year under Mazzulla, and the team has won at least 57 or more games each time and reached at least the Eastern Conference semifinals annually.
