One of the most critical moments in this game occurred late in the second period. The Lightning led the Red Wings, but the lead was only a one-goal advantage. That’s because the Wings had rallied from a 3-0 deficit to score back-to-back goals in the second period. But just over a minute after Darren Helm netted Detroit’s second goal, the Red Wings took a pair of penalties 12 seconds apart. Those infractions gave the Lightning a five-on-three power play lasting 1:48. They cashed in. Tyler Johnson set up Nikita Kucherov at the side of the net for a tap-in goal.
