Tatum: Mazula is the best coach in the world. He not only knows the ball but also cares about everyone.

Today, Celtic player Tatum participated in the ESPN "First Take" channel program.

Speaking of the new season, he said, "I like the current players of our team. I love the core team we still have, they have won championships together, plus some new members. We still have the best coaches in the world."

Speaking of Mazula, he said, "Excellent coach. One of the best people I have ever come into contact with. I love Joe very much. I think as a part of the coach, you have to know the game, know tactics, manage the adjustments in the game. He is excellent in this and our coaching staff is great. What Joe is better at is that he really cares about his players. He lets you know this every day, and it takes time and trust, and over time, you have to win that. And Joe has won the trust of everyone on our team. He really cares about each of us and basketball."
