Nashville, Tenn. — Remember your first time? This city has dubbed itself Smashville. It’s kind of cute, don’t you think? Hockey is as fresh and exciting and sloppy here as an adolescent kiss. Try to stay classy, Smashville. I know it’s difficult. For example: What was that elbow Nashville forward Ryan “The Ripper” Johansen delivered Thursday night to the head of Avalanche defenseman Tyson Barrie with three minutes, 30 seconds remaining in the second period of an NHL playoff game? It was a blindside cheap shot, that’s what. “It hurt,” said Barrie.
