Throatguard suggestions - Pain in the Neck

Recently, Richard Zednik had his carotid artery cut open and was immediately rushed to the trainers followed by a trip to the hospital. This bizarre event has stirred up talk of mandatory throat guards to be worn at all times during the game. First off, this protection would have to flexible, so how strong would it really be? Would it be strong enough to hold up against a razor sharp skate? Secondly, this is only the second time this has happened in the last 20 years going back to the Clint Malarchuk incident from 1989. No one would wear the throat guards and personally, I think it was a dumb idea to begin with.
