NBA Notebook: Jayson Tatum's full return, Keyonte George re-signs, and Knicks roster moves

Next season will have a lot going on. The Boston Celtics completely changed their franchise's future outlook when they traded Jaylen Brown. And the change is going to begin right away.

Payton Pritchard will have more responsibility. Paul George is in town. Same with Mitchell Robinson and Mike Conley Jr. Boston's young core will have more opportunities to shine. But perhaps the most intriguing storyline of them all has been relatively underdiscussed.

It didn't look like the Tatum of old. The pre-injury Tatum. The version that earned All-NBA First Team honors four years in a row. Based on his supposed nerves, that makes sense.

But if Boston wants this new team to work -- this post-Brown group -- Tatum needs to
