According to Robert over at Jewels From The Crown, the Kings out-attempted the Devils 13 to 10 at even strength in the first period. In total, the Devils had 17 shot attempts to the Kings' 21, so it’s not as if the Devils really took advantage of their two full power-play attempts in the first period.
Overall, it was a pretty even period, but the post has been the only thing that’s kept Los Angeles off the board so far. The Devils have a bit of penalty time to kill off early in the second period, but it appears as though they’ll need to pick it up a bit overall on special teams to stay in this game. Then again, as the clock winds down in the second and third periods of an elimination game, special teams might become less of a factor. We’ll see.
