That's a bit premature. I will say that he is the best young player in the playoffs right now. Yes Donovan Mitchell was impressive, but he couldn't get his team into the conference finals. Tatum did that. Tatum's run isn't over yet either.
This could well be known as Tatum's coming out party, especially IF we can knock out the Cavs. It would be remembered as a legendary series, and Tatum will need to play at an incredibly high level. I'm sure Stevens is plotting a great master plan right now. If the Celtics get through to the Finals... well that would be the best coaching job of the past decade!
