Jayson Tatum is embracing the start of his 10th NBA season with the Boston Celtics, expressing enthusiasm for every aspect of the preparation process, including training camp. The team is currently finishing its camp with a three-day session in South Carolina before its preseason opener against the Cleveland Cavaliers on Thursday.

Tatum has taken an active role in fostering team chemistry, organizing offseason workouts and golf outings that welcomed new acquisitions Paul George and Mike Conley. This effort aligns with coach Joe Mazzulla’s ongoing mission to shape the newly assembled Celtics roster into a championship contender. Mazzulla, now in his fourth season leading the team, has developed a close working relationship with Tatum, who has praised the coach’s influence both on and off the court.

“I love Joe,” Tatum said. “He’s impacted me, my life on and off the court... He just cares about you as an individual and really shows that every single day.”

Tatum, who returned to play last March after recovering from a torn Achilles tendon sustained the previous season, reports feeling fully healthy with no practice restrictions currently in place. Though uncertainty remains about whether he will have game limitations during the regular season, Tatum said his confidence and conditioning have significantly improved since his return.

“It’s a long journey from the injury I had and I feel great,” he said, reflecting on his progress 16 months post-injury.

Meanwhile, two-way player Dillon Mitchell is focusing on improving his jump shot as he adapts to the Celtics system. Originally known for his defensive capabilities, the former St. John’s standout aims to develop into a reliable “3-and-D” contributor—a player who combines strong defense with the ability to knock down three-point shots. Mitchell noted considerable changes in his shooting form and growing confidence during the early stages of camp.

After getting drafted in June, Mitchell and fellow rookie Chris Cenac hit the ground running, attending practice facilities immediately upon arriving from the airport. Cenac, 19, has concentrated on refining his perimeter shooting and learning the nuances of the NBA game from veterans such as Mitchell Robinson and Neemias Queta.

“The NBA is more attention to detail, little things,” Cenac said. “It fits my game perfectly and I’ve been having a lot of fun, playing with these guys, learning from them.”

The Celtics are currently determining final roster spots as they continue camp in South Carolina. One two-way contract position remains open, with players Devin Carter, Tucker DeVries, and Milos Uzan competing for the spot. Former Maine Celtics player Hayden Gray, who appeared in one game last season with Utah Jazz, has returned to the organization and may see time with the G League affiliate. Meanwhile, the franchise has officially appointed Phil Pressey as the Maine Celtics head coach for a second straight season.

As the preseason approaches, the Celtics aim to solidify their rotation and establish continuity heading into what is expected to be a critical campaign for the team’s aspirations.
