From The Athletic's story:
Following the first game this season against Udoka’s Rockets, Tatum suggested the coach brought the Celtics an edge they needed during his lone season with the organization. When Boston hired the coach in 2021, after Brad Stevens moved to the front office, Tatum said it was a good time for a change.
“Brad had done an amazing job for 10 years or whatever it was,” Tatum said. “Sometimes, you just need a different voice and a different style of coaching. I think Ime, he’s big on toughness and physicality and taking on the challenge and going at people. And that’s what we did that year, right? We had a tough start. But him as our head coach, he never wavered and we turned our season around. We was hungry. And got to the Finals and came up short. We loved to have him around. He’s an amazing person, amazing coach.”
Tatum said he has been blessed to play under Stevens, Udoka and Mazzulla.
“I would venture to say I’ve been very fortunate with the organization I’ve been with, with all the teammates that I’ve had, and I’ve had three of the best coaches I could have possibly had, especially at the time in my life,” Tatum said. “Brad believing in a 19-year-old kid and teaching me about the NBA and the ins and outs. At times I was frustrated with Brad and I wanted a bigger role or whatever, but I appreciate the relationship that me and Brad have and how he allowed me to grow through that process. Ime, that one year was special. First time I made first-team All-NBA, went to the finals, at that point it was the best season I had. And he instilled something in the organization that was needed at the time. Obviously, Joe, with what he’s done with this group and leading us to a championship, so I’ve been very fortunate to have three of the best coaches, those are three of the best people that I could have had and helped me on my journey.”
