Mike Sullivan finally made substantial changes to the Pittsburgh Penguins power play.

As the Pittsburgh Penguins head into their bye week, their power play sits at an abysmal 13.1% success rate. It's been their Achilles heel all season, and head coach Mike Sullivan finally reached a breaking point.

Late in their game against the Florida Panthers, the Penguins made substantial changes to their top power play by removing Evgeni Malkin and Erik Karlsson in favor of Kris Letang and Valtteri Puustinen.

In addition, Sullivan deployed the two units evenly throughout the remainder of the weekend. The top unit played 3:21 while the second unit played 2:39. It's been a small sample size, and they didn't score on three chances, but the optics are much improved since they shifted the lines.

The numbers match the eye test with the Penguins' shot attempts (3.5), shots on goal (1.3), and scoring chances (1.8) per minute increasing significantly over their previous month's performance per Natural Stat Trick. 

Time will tell if Sullivan and the Penguins continue to run with these combinations after the All-Star break, but at least early on, they have found some energy and life with this new look.
