Kyrie Irving appreciates what he calls "the innocence of the game" during Boston's 15-game winning streak. In his first season with the Celtics after demanding a trade from Cleveland, Irving is enjoying the torrid start because everything feels so new. "Most of us have never been on a winning streak like this," he said. "I don't know if we even know how to pay attention to all the hoopla that goes on in terms of the excitement of it. I just think that every single game we take it as a challenge." Irving scored 30 points, Jaylen Brown added a career-high 27 and the Celtics beat the Atlanta Hawks 110-99 on Saturday night. reas more http://www.espn.com/nba/recap?gameId=400974981
