The NHL, correctly for once, doesn't want egregious conduct that happens after a possible reviewed play to go unpunished, so by rule any penalties that happen still get called.
I'm fine with that.
If they want to change it so that it can't result in a penalty shot (because they're essentially after the whistle penalties at that point), I'd be ok with that.
I'm also in favor of changing the rule so that they can't review an offside entry if more than XX seconds have passed since the entry. Because at that point it really didn't impact the play.
