I've never been a fan of refs "swallowing the whistle" just because it's an important game. If a penalty is a penalty, call the f***ing penalty. I can see the incidental kind of trips and such being let go, even though one in the OT was a blatant penalty that probably should have been called. But 7 guys on the f***ing ice as the puck goes through them all? Yeah, you have to call that shit. By not trying to impact a game result with penalties, the refs ultimately impact the game result by NOT calling penalties. So they're still impacting the game result. It's so stupid.
