There isn't a hotter goalie right now than Anaheim's John Gibson, who has stopped 98 of 101 shots. The Ducks are 3-0 this season because they have given up just three goals in three games. The Ducks are a dead-nuts Under team right now with a sub-par offense and a strong commitment to defense. If you go back to preseason, the Ducks are a perfect 27-for-27 in killing off power plays, including 7-for-7 in the regular season. 
The Penguins have a cluster injury on offense with two centers and two wingers out the most prominent being Evgeni Malkin. The multiple injuries really showed in the Penguins' last game when they could manage only one goal versus Winnipeg this past Tuesday at home.
Pittsburgh takes to the road for the first time this season following this game. So the Penguins should have their defensive intensity up knowing their offense is down players and this is the final matchup of a four-game homestand that has proven disappointing at 1-2.
