Jaylen Brown has become a fixture in Boston sports. Over the past six years, he and Jayson Tatum have formed a solid duo. So far, they have led the Celtics all the way to the NBA Finals. In the time since, they've made it back to Game 7 of the Eastern Conference Finals. Also, the Celtics currently hold the NBA's best record. None of that mattered in their last game, which was a blowout home loss. But Brown had bigger problems, as a prankster pretended to be him, and took photos with the fans.
