Sam Cassell’s comparison of Joe Mazzulla and Doc Rivers offers an insightful look into the contrasting coaching styles that have both led to success in the NBA.
Cassell, who has had the unique experience of working closely with both coaches, highlights that Rivers is a strong, decisive leader who relies on his extensive experience and success. He isn’t afraid to assert his authority but is also open to advice when necessary, showing a willingness to adapt when his assistants suggest that he ease up.
In contrast, Mazzulla, who was relatively new to the head coaching role when he took over the Boston Celtics, had to grow into his leadership position. Cassell notes that while Mazzulla was immediately strong with the X’s and O’s—demonstrating a deep understanding of the game’s tactical aspects—he initially lacked experience in managing NBA players on a personal level. However, Mazzulla’s approach is more collaborative within the coaching staff, valuing the opinions of his assistants before making the final call.
Cassell’s reflections emphasize the different ways in which leadership can be effective. Rivers’ approach is more authoritative and experience-driven, while Mazzulla’s style is adaptive and inclusive, ultimately leading to the same goal: success on the court, as evidenced by the Celtics’ 2024 championship win.
