Jayson Tatum: Always first and foremost taking care of my body, in the weight room working on my legs and making sure my core (is good), changing my diet, trying to eat better. The basketball stuff is easier to figure out, I’ve been doing it so long. I think your body is what keeps you up here. Celtics Wire: How’s the shoulder injury from the Finals doing? Feeling any better? Jayson Tatum: Yeah, it feels a lot better, it got a lot of time to rest that it needed. So, it definitely felt a lot better.
