Jaylen Brown isn’t afraid to admit the vibe around the team has improved significantly. The C’s swingman opened up about the changes in a conversation Wednesday with NBC Sports Boston’s Abby Chin. “It’s not perfect. It’s not like utopia in our locker room,” Brown told Chin. “But it’s great. Nothing is ever going to be exactly the way that you want it to be. That’s the good thing about a family, people argue but you still love them at the end of the day. “Everybody always compares things to last year but — to be honest it is a better environment, but there’s ups and downs. It’s part of the journey.”
