Left wing Dustin Brown didn’t want to dump on the Kings’ plans for their big opening-night extravaganza Monday at Staples Center. The New York Rangers are in town for the home opener, but it’s just another game, as far as Brown is concerned, and with good reason. Said Brown after Sunday’s practice: “Once you’ve won a championship, it’s not the same. I mean, home openers were a lot more exciting before we won.”
