They don't need multiple camera angles any more than we did, and we at home could plainly ****ing see that he was hurt, the rule was written in there like it's written in there for a frickin' good reason. It's not that hard to go in quickly and take a look if they thought for a second that he may have been faking it. All refs can move pretty quickly, they wouldn't be NHL refs if they couldn't.
They're not idiots, but they are acting scared, especially after what happened in that Knights/Sharks game. A former ref said in a radio interview that it's ingrained to them to make an error of omission rather than commission. But it's tipped way, way too far now. The thing is that the refs who screwed up were indeed punished, but not in any tangible or concrete sort of way that clears things up, so the refs themselves are still kinda confused as to whether the league has their backs or not.
I'll readily admit that the hesitancy to make that call was understandable...but that's still not an excuse.
