I don’t think that the team loves it but they accept it.His body language will always suck, and though it bothers me in the moment, that is just who he is. What I see from how the team likes his kid, embraces him it may not be that important. Now if he carried himself like Jimy Butler or Curyy (two different but inspirational stars) it may make the Cs a bit better.
A bigger concern is him figuring out when to exert himself and dominate the ball and when not to. It is possible, since this team can score his effort on D may be more important. I worry if he isn't scoring he doesn't just accept he can do his part to win on the boards and on D.
I live in Tampa and when the Raptors were playing here, because of COVID restrictions in Canada, Austin Ainge played golf at the course that I belong to. He played with one of the pros (from Maine) and another member (from Mass). I wasn’t there but apparently Ainge said that the organization was really trying to hammer home to Tatum the importance of hustling to get back on defense and improving his body language. He said that it was ongoing and Tatum wasn’t taking to it as much as they would have liked
