Brandon Bussi stopped 15 shots for his first NHL shutout as the Canes beat Calgary, 1-0, in overtime for their second straight win.  Nikolaj Ehlers tapped home a feed from Taylor Hall 2:52 into overtime giving Carolina the win.  Bussi didn't have a lot of work, but what he had tested him.  Odd man chances that saw him stop Blake Coleman and Morgan Frost, plus three different breakaways.  He's now 7-1-0 in 8 starts this season -- the first starts of his NHL career.  Shayne Gostisbehere continues to play some of the best 2-way hockey of his career and it was a noticeably good night from Alexander Nikishin -- who could have scored 2 or 3 goals.
