Joe Mazzulla has been a head coach before, and he learned something that might make him as prepared for his new role with the Celtics as he can be.
Specifically, Mazzulla knows he’s not ready.
After all, how could he be? Last year, Mazzulla was one of just two holdovers from Brad Stevens’ tenure as head coach, learning how to coach under Ime Udoka. Now, after the shocking news that Udoka has been suspended for the season, Mazzulla — who previously coached at NCAA Division II school Fairmont State — has been thrown into a head coaching role on an NBA team that hopes to make another deep postseason run.
