Rick Nash is showing exactly what the Rangers hoped they were getting when they pried him away from Columbus. New York is riding high on a three-game winning streak, but instead of being able to fully celebrate their good fortune and the improved play of their newest star, the Rangers are holding their breath as they wait for medical news regarding key defenseman Marc Staal. Nash broke a third-period tie and added an insurance goal in the Rangers' 4-2 victory over the Philadelphia Flyers on Tuesday night. Any feelings of euphoria were greatly lessened because of concern regarding Staal, who appeared to be struck in the right eye by a deflected puck 5:45 into the third.
