Helm was at the centre of it all, assisting on DeKeyser’s tying goal and Daley’s go-ahead score before finding the net himself on a breakaway late in the third period.
Sebastian Aho scored for the Hurricanes, who snapped a three-game win streak. Scott Darling made 34 saves while losing for the sixth time in his last seven starts.
Aho’s power play goal midway through the first opened the scoring. Justin Faulk’s slap shot from the blue line nicked Mrazek’s glove and fluttered over the Detroit netminder’s back, and Aho knocked it in the air and into the net.
Helm and the Red Wings took over from there.
DeKeyser tied it before the period was out. Aided by a screen from Frans Nielsen, DeKeyser took a pass from Helm and ripped a slap shot that beat Darling to his blocker side.
Daley put Detroit ahead 5:06 into the second. Helm came up with a Hurricanes turnover deep in his own zone, raced down the ice and dropped a pass back to Daley at the point and he wound up and fired a vicious slap shot over Darling’s glove.
Nyquist provided insurance in the third when he snapped a wrister over Darling’s glove with 12:15 remaining.
Helm added the final blow when he came out of the penalty box and picked up a loose puck at centre ice for a breakaway, firing a slapper over Darling right in front of his face.
