Tatum is taking it all in stride. Even the criticism. The Celtics, coming off a disappointing .500 season, have opened this season at 12-11. Tatum knows how it is for players of his stature. When things go right, the praise is thick. When things go wrong, the blame will point straight at him. “I think that’s just the world we live in,” Tatum said. “They’re always just going to talk about what you’re doing. Never about what you’ve accomplished and stuff like that. It’s just what you’re doing right now. And I think that’s what kind of drives some players. It’s like, don’t be complacent. I’m always focused on what I can do next. And I’m sure the narrative will change when we get to the championship one day. So we’ll see.”
