Joe Mazzula is grossly underpaid and has 2 years left on his contract.

Joe Mazzulla only makes $4.7 million per hear which is a fraction of other top coaches around the league. The Celtics better go all in to keep Mazzulla for the next 5 years at least. That guy is a machine, he is so focused on winning he didn't even crack a smile in his post Finals interview. He's all business and all about his team and his Faith. Congrats to him and the Celtics. If they can keep that team together with Mazzulla, good luck to the rest of the league.
