In fact, the main reason is that he really can't control his teammates. Maybe it's really hard for him to be a team leader, at least he can't convince those young players. In yesterday's Celtics-Raptors game, at the end of the game, Owen hit a key three-pointer against Leonard, which opened the score to five points. This three-pointer also determines the direction of the whole game.
Owen was very happy after scoring, and even made Kobe's classic moves. His teammates also got together to celebrate with Owen. But in this photo, as Owen's best assistant, Tatum is isolated from them. I saw Tatum walking to the bench alone, with no expression on his face.
For Tatum, his current role is very similar to the Cavaliers' Owen. As a young man, he is very dissatisfied with his role. The most obvious temperament of young people is unconvinced, so Tatum is not as excited as other teammates at this moment. Seeing us here, I believe everyone should know why Owen suddenly apologized to James and asked about his experience. Of course, the outbreak of this incident may also be Owen's warning to Tatum: don't do things that you regret.
