Perry's line was more or less the only one that produced anything offensively along with Getzlaf. At the lack of some defense tho. Rakell got burned in the circle as well. But not his fault that Manson turned over the puck for the first goal, and when Patty scored, Getzlaf was still on the ice, so there goes that + for him as well. But -4 is not a good stat anyway you look at it. But the trouble started first and foremost in their own zone when the d couldn't handle Pens forechecking. Forwards didn't do their job to help out either. Only Keslers line that was solid defensively (as usual) but they on the other hand were invisible in the o-zone.
And that they couldn't handle Pens speed in the midzone / the transition game. Lots of chasing going on for lots of times during the game. Turnovers and sloppy play didn't help either.
