The Penguins' power play hasn't been a strong suit of theirs this season, and that's been especially true in the last two weeks.
The change they made in Saturday's morning skate ahead of their 7:08 p.m. meeting with the Blues may just provide the spark the team needs on the man advantage.
The Penguins scored two power play goals in their 6-4 win in Minnesota on Nov. 17. Their next goal on a power play didn't come until Jake Guentzel's tally in the Penguins' 4-3 win over the Golden Knights on Thursday, a goal that snapped the team's six-game goalless streak on the man advantage, a stretch in which the Penguins failed to score on 17 consecutive power play opportunities.
