Boston Celtics head coach Joe Mazzulla prepares for a make or break fourth season. With assiduous leadership from his sidelines and peer-leadership from his starting 5, Tatum points to the galvanizing effect of Brown. As he adjusts to a new roster that has seen plenty of turnover, Mazzulla is still highly optimistic about the path forward. During the off—very, very off—season, the coach got to build relationships with other coaches and take time to think about his new position. These experiences have informed his approach as the new NBA season approaches.
Presumably, Mazzulla sees Jaylen Brown’s confidence-inspiring vocal leadership as a critical element for success for these Celtics. He knows how badly they need veterans who can provide direction and inspiration to their fellow workers, particularly in trying, questionable times. Brown’s improved, more assured form of communication should be key, especially as the new-look roster re-establishes chemistry with each other.
In addition to focusing on his players, Mazzulla has spent valuable time with Los Angeles Rams head coach Sean McVay, another Italian coach who understands the pressures of leading a professional sports team. Each of their conversations, she says, have equipped her to find that right balance between competition and the personal life. Mazzulla remarked on their shared heritage, saying, “It’s always refreshing to connect with someone who understands the unique challenges we face in our respective sports.”
That same summer, Mazzulla reached out to another friend. Their deep commitment to family is another thing they have in common. Mazzulla touched on Geno’s friendship with his wife, Sheila, and on his tender-heartedness as a grandfather. These interactions have reaffirmed his steadfast belief in the necessity of upholding genuine, deep personal connections alongside the tough, firm, no-nonsense nature of coaching itself.
As he looks ahead to his first full season, Mazzulla has been in frequent communication with Manchester City manager Pep Guardiola. These conversations, facilitated every few days through the summer by Stevens, have given Mazzulla perspective and context on leading and making decisions in high-stakes situations. Guardiola’s experience in managing world-class athletes has given Mazzulla insight on how to create a cohesive unit that embraces adversity.
In looking back on his first year as head coach, Mazzulla called it a humbling experience, one in which the lessons came pouring in. And while he recognizes that coaching is one of the most high-pressure and high-octane careers out there, especially when you’re not winning the way you need to win, “It’s hard when you don’t win or you let someone down to remember that there’s gratitude in that love,” he explained. “I think this is the ultimate sign of love and competition.”
Whether Jayson Tatum’s temporary absence will affect the Celts remains an open question. For Mazzulla, this is another test and opportunity for development. He stated, “I don’t look at it as it’s unfair to the people, our team, our organization to look at this as anything other than just another NBA season.” His determination to approach every game as an opportunity to grow shows his champion mentality.
Though serious and competitive, Mazzulla seems to genuinely appreciate the relationships he’s cultivated with his players and organization-wide staff. Realizing that trust underpins every successful endeavor, he is committed to deepening these relationships. It’s clear to him that all his players need to feel supported as well—now, when things are messy and vague, and in the future.
To strengthen team bonds, Mazzulla organized a pickup basketball game against the Boston media, illustrating his belief in building camaraderie through shared experiences. This initiative provides a fun, non-competitive distraction from serious drills and training exercises while building camaraderie and collaboration.
Like every team, the Celtics are looking forward to yet another tough NBA season. On the culture front, Mazzulla is clearly committed to creating a culture of resilience and togetherness in the locker room. His approach has a remarkable understanding of the challenges faced by someone trying to coach at this level. He is committed to establishing an atmosphere in which players can excel.
