There is only one way for the narrative to change for Carmelo Anthony, and it’s a simple task: win tonight. It doesn’t matter if he shoots 14-for-16 or 4-for-26, doesn’t matter if he carries the Knicks or goes along for the ride. The specifics will be worked out later. This is what can happen: The Knicks can beat the Celtics, in Boston. They can advance to the second round of the playoffs for the first time in 13 years. And Anthony can write his team’s name on a winning playoff bracket for only the third time in his career. After all the craziness and zaniness of the past seven days, there is room for a satisfying ending for Melo. Win the game. Beat the Celtics. Survive and advance. And do it now. “It’s not only just Melo, it’s our team as a rule,” Knicks coach Mike Woodson said yesterday following a brief practice session. “This is the first time we’ve assembled this team. There’s a lot of guys who’ve played a lot of basketball but this is our first time together. Our goal has been to get out of the first round and that hasn’t changed. And he’s a big part of it.” That’s what the coach has to say, of course, because every coaching mantra always involves some iteration of team over self. But there is no mistaking who carries the biggest burden in a moment like this. Anthony would anyway because he is the biggest name, the biggest star, the biggest paycheck.
