Sunday's 6-2 rout at the hands of the San Jose Sharks was just the latest illustration of the team's penchant for penalties, with five minors leading to two power-play goals for the Pacific Division rivals.
Of course, the Penguins boast the top power-play unit in the NHL, and the Sharks aren't far behind at No. 5. The Ducks are ranked No. 9 in penalty-kill percentage.
"You can't give the opposition's power play five chances to practice against you," coach Randy Carlyle explained.
