PHILADELPHIA — Jaylen Brown likes to say that the start of something new must mean the end of something else. But as much as he wants to embrace his new chapter in Philadelphia, there are still faint traces of sadness. "I'm focused on what's in front of me," Brown told media at his introductory press conference on Thursday afternoon. "To be honest, I'm moving on." I just choose to not focus on…I choose to focus on what I focus on," Brown said of the difficulty of the last six weeks.
