This is why head shots still happen. If the player's union isn't taking this seriously, then you can sure as hell bet they're not saying a word to players in their annual preseason visits. How strange this all works when you have these factions pulling in different directions.
If I'm an owner I want headshots out completely. Even if I'm the coldest, most bloodless money hungry SOB in the league I can't think of one good reason why I wouldn't want that part of the game cleaned up. Injured players cost money and more incidents raise insurance and medical costs. For those reasons alone I can't see why any owner would treat this lightly never mind losing a star player (or any player) for a good chunk or the whole season.
Then you have the player's union whose sole existence is to represent the players and they're talking out of both sides of their mouth on this issue.
Incredible
