Joe Mazzulla is no longer a rookie coach. He seems more comfortable now as he approaches his second season with the team. He has a revamped staff. He had an offseason to prepare, which wasn’t the case last season.
He’s finding ways to make his mark on the team, and it’s been noticeable to Celtics forward Jayson Tatum.
“I give Joe a lot of credit. I’ve seen the growth,” Tatum said. “Not that I didn’t think he did a great job last year, he just has more time to prepare. He was able to get a staff that he felt supported him in the best way, and he’s helped change the culture in a lot of ways honestly.
