The Penguins' power-play currently ranks No. 14 in the NHL with a 21.4% success rate on their opportunities.
For the season, the Penguins are a top 10 team in the rate at which they attempt shots and generate expected goals, but some of that is buoyed by a strong showing right out the gates.
Over their current six-game losing streak, though, the Penguins haven't been doing nearly a good enough job to take advantage on the power play. Since the skid began, the Penguins are roughly league-average with how frequently they are shooting, but rank toward the bottom of the league in how many of those attempts are actually making it on goal.
