I don't think it's as bad as Kronwalling, myself. Allowing those hits with the insane justification that he isn't at fault because he isn't consciously aiming since he's going backwards reeked of pro-O6 bias. The Trouba hit can be argued clean (I haven't decided how I feel because apparently I still harbor massive anti-NJ bias so I'll just not bother), but there isn't any universe where Kronwalling should have been reasonably unpunished.
If Kronwall were a Flyer, I am positive he gets lit up for it. The people running the league will still proudly profess an ongoing hatred of the Flyers because they were a mean team for a couple years 50 years ago and they were raised to hate them.
