I think the part that is confusing me the most right now, is not really why the refs were swallowing the whistle when it came to facemasks, personal fouls and pass interference, but moreso about why the fans were allowed to blow their whistles in the stands!! Maybe I'm way behind on the rules, but I always thought that fans weren't allowed to blow whistles like that and it could end up as a penalty for the Home team. Has that changed? Was it never a rule to begin with? Something has to change on that. It's not good for the game and it's actually dangerous for the players. Nobody is talking about it though.
