Joe Mazzulla, head coach of the Boston Celtics, uses the artificial intelligence assistant Claude every day. He does not use it to draw up plays or set lineups. He uses it to help organise his thinking, testing ideas and working through problems before he makes a decision.
The source material frames Mazzulla's habit around a simple reason: he wants a sounding board that will challenge his assumptions and help him reach clearer conclusions. The tool is used as a thinking partner rather than as a source of final answers, and the coach remains responsible for every call he makes on the bench and in the front office.
The account is notable because it comes from one of the most high-profile figures in the NBA, a coach who has led the Celtics to a championship. It presents AI not as a novelty or a shortcut but as a routine part of preparation, in the same way that video review and statistical analysis have become standard across professional sport.
The source describes the habit in terms of daily practice rather than occasional experiment. Mazzulla's use of the tool is presented as ongoing, a fixed part of his routine rather than a one-off trial, which suggests he has found a consistent role for it in how he prepares.
For business leaders and managers outside sport, the example offers a practical point. The value Mazzulla describes lies less in the technology itself than in using it to structure reasoning and to question one's own instincts, a use that applies equally to executives weighing strategic choices and to teams making high-pressure decisions under time constraints.
