Having better equipment for safety is one thing, but radically modifying the rules and changing the game, arguably making it less interesting, that is bad. And it isn't a matter of an employer doing "whatever they fuck they want to their employees". It's a matter of preserving an interesting game for the fans, and making that a higher priority than the stupid safety thing. I say again, if any player thinks the risk is too big, he can be like Chris Borland and just quitand walk away from that shit ton of money.
