Here's a new twist on the Oklahoma City Thunder's budding rivalry with the Dallas Mavericks: With a game coming down to crunch time, Dirk Nowitzki didn't want the ball. Instead, it was Russell Westbrook who shrugged off a shaky start and closed out a Thunder victory. Kevin Durant scored 40 points, while Westbrook added eight of his 16 points in overtime to help Oklahoma City beat Dallas 111-105 on Thursday night for the Thunder's 11th straight win at home.
