Evan Rodrigues and Alex Newhook also scored for Colorado, which was outshot in every period of regulation and 48-15 overall. It was the first overtime victory in three chances this season for the Stanley Cup champion Avalanche.
Pavel Francouz made 46 saves as the Avalanche beat the Hurricanes for the second time in six nights.
Necas scored the tying goal, his eighth of the season, with 9:37 to play in regulation. It came with Francouz trying to defend the net without his stick. Necas made a move on the right side.
Aho’s eighth goal came 7:14 into the second period when the puck came back to him after an initial launch didn’t make it to the net and Necas helped recover the puck.
Newhook put the Avalanche ahead 2-1 at 14:20 of the second period.
Rodrigues scored the game's first goal on a power play after the Hurricanes failed to clear the puck. That added to the production of Colorado’s league-best power play.

Hurricanes forward Andrei Svechnikov played his 300th career game, becoming the first member of the 2018 draft class to reach that mark. In those games, he had a total of 227 points (101 goals, 126 assists).
