The Boston Celtics' coach, Joe Mazzulla, is criticized for his lack of in-game adjustments, particularly his reliance on three-point shooting and failure to utilize post-up plays. Despite a championship, his coaching is questioned when facing aggressive defenses, with suggestions that he needs to be more adaptable like legendary coaches Phil Jackson or Pat Riley.
Impact: Medium. Mazzulla's perceived inflexibility could hinder the Celtics' playoff success, especially if they face teams that can exploit their offensive weaknesses.
