Jayson Tatum admitted that he struggled last season with the Boston Celtics, describing his performance as "funky."

"Last year was kind of funky in all aspects. I understand that. I acknowledge that, and I'm just trying to be better this year," said Tatum.

Tatum ranked last in efficiency among 96 players who had at least 100 isolation plays last season, according to data.

Tatum added that he focused his work last offseason towards efficiency.

"Focus on getting to the basket much more. Shoot more 3s, and layups, and free throws."
