I'm going with Curtis McElhinney. As fans we were burned pretty badly by Darling's play. You could tell the team actively played worse in front of him. When the switch was made to Mcbackup it was like night and day. He was calm in net, made timely saves, and most importantly was not the specific reason why we lost games through backbreaking soft goals. Before Mrazek went out of his mind, Curtis changed the direction of this franchise from lose for Hughes to the hottest team in the NHL for almost two months and helped fill our building again.
Curtis plays solidly -> Team has confidence to win games they shouldn't -> They recover from the awful start -> Fans start to come back and gives team energy -> The rise of Mrazek
I don't fault him for his body breaking down. We knew what we were getting when he arrived. I wholeheartedly believe that we're not able to play tomorrow if he doesn't start the ball rolling to save our season. I don't think he was the most impactful, that probably goes to Nino, or the best, that goes to Aho, or even the most underrated, which goes to Teuvo. But for a two month stretch he's the most valuable Hurricane we've had in years.
