Not Tatum fault , he can’t do it all, Celtics are too predictable, VERY poorly coached , teams gang up on Tatum , poor team offense …..it’s a mess . Strong leadership and change of role players needed to really contend . Celtics are notmentally solid on court and playing team ball . Too relaxed and cool is not going to beat the well coached teams . You have to have the dog in you and determination to force your will on the opponents and not let up.
