Look, I don't complain about refs, my post history might have 10 posts were I do this but the numbers from Corsica are pretty insane and can't simply be chalked up to "of course the Pens get more PP's they possess the puck more" because that is NOT really the case. This season in the playoffs they are 6th in 5v5 CF%, last season they were 15th, '15-'16 they were 7th, season before 5th, etc.
No tin foil hat crap from me but the numbers are the numbers, Pens might deserve every PP they get and that's fine, but there is zero chance they are not committing any either.
