Boston gave Tatum the supermax rookie extension. He’s their designated star, even if Brown was the better player in June and has been instrumental to the team’s success. Tatum’s input always matters because they’re building around him. Brown and Smart have undoubtedly been a part of that foundation, but they’ve also been in trade rumors as long as they can remember. Not Tatum. He’s deeply entrenched, though he says he’s staying out of it anyway. “The cool part about his job is Brad don’t tell me how to do my job anymore. You not the coach,” Tatum said with a sly grin. “He lets me do my thing. I let him do his thing. In all honesty, that’s his decision and that’s his job.”
