Nashville coach Barry Trotz insists he knew nothing of Detroit's loss just as his Predators went into the third period needing a win of their own to grab back the chance of landing home-ice advantage to start the playoffs. His Predators sure responded as if they did. Pekka Rinne made 28 saves for his fifth shutout of the season, Francis Bouillon scored at 4:28 of the third period, and the Predators beat the Dallas Stars 2-0 on Thursday night for their third win in four games.
