If Jayson Tatum and Jaylen Brown do harbor some level of animosity toward each other now, that is truly a shame.For so long, they were a shining example of how much an NBA superstar duo could survive together. They were proof that not every team should make wholesale changes at the first sign of trouble. Their partnership stood as a symbol of resilience and determination.Maybe their relationship is still in a good place after the Celtics traded Brown to the Philadelphia 76ers, but the two have made it easy to speculate otherwise. The latest possible hint of dissension came from Tatum, who took what many perceived as a dig at Brown while speaking recently at a camp in St. Louis.Where does the Jaylen Brown trade rank in NBA history?The Athletic NBA Staff and Jeshua Kidd“Being a leader doesn’t mean you know it all, right?” Tatum said in a speech shared on social media. “I don’t know it all. I’ll be the first person to say that. Being a leader is being comfortable with raising your hand, like, ‘I don’t know, can you explain that to me?’ ‘I don’t know XYZ. I want to learn.’ Being around somebody that feels like they know it all, I don’t want to be around that person. I don’t want to be the smartest person in the room. I want to learn from somebody else.”Tatum could have simply been trying to give helpful advice to a gym full of young players. Despite being one of the NBA’s most decorated stars, he has remained an extremely coachable player. He constantly seeks out additional knowledge about the game, his body and anything else that could give him an edge on the court. The topic he addressed in the video, which was initially shared on his foundation’s Instagram page, is a message he clearly believes in.“Asking questions, being vulnerable — it is OK not to know something,” Tatum continued. “It’s not OK not to ask questions and not to want to learn. Because it’s not how we’re going to get better at anything in life. Not just basketball. Whatever you want to do in life, you have to ask questions. You have to listen. You have to learn.”
