European media Basketball Sphere reported that Serbian coach Uroš Dragicevic, who served as a member of the Celtics coaching staff during the preseason, talked about Tatum's professional attitude.

He said: "I told them that Tatum looks like he can play tomorrow. He has recovered amazingly after a serious Achilles tendon injury. Sprinting, weightlifting, personal training, everything. As the core of the team, MVP, and has his own sneaker brand, he does not have to arrive early every day, but he still has breakfast at the venue on time at 8:45 in the morning, works out, and participates in the team Training, lunch, watching videos, and recovery. Go all out every day, a true leader. "

"Tatum once wanted to visit Duke University on his day off, and asked about the training time on Friday to ensure that he could come back on time. Mazzula agreed and told him to come back before 12 o'clock. "
