Necas has scored five points in the past two games; he had a goal and an assist in a 7-2 victory at the St. Louis Blues on Saturday.
"It always builds your confidence more and more when the puck goes in and you feel good about yourself," Necas said. "(It) always helps, but [Carolina coach Rod Brind'Amour says] everybody has to play two-way game and if you play good in your own zone, you're going to get chances in the other."
Brady Skjei had a goal and an assist, and Frederik Andersen made 25 saves for the Hurricanes (44-15-7), who moved five points ahead of the second-place Pittsburgh Penguins in the Metropolitan Division and will try to sweep a three-game road trip at the Tampa Bay Lightning on Tuesday. Max Domi, Vincent Trocheck and Teuvo Teravainen each had two assists.
"I think every game from now until the playoffs is gearing up for the real stage," Domi said. "Every game's big, it doesn't really matter who it's against. Obviously, that's a good team over there, we know that. We were good tonight, so we'll take the win and got to get ready for the next one tomorrow against Tampa."
