Thats a good idea, and I think everyone should be wearing them. For the record, I thought they should be required equipment before the Zednik accident.
The kids wear all the other required equipment without complaining, and this shouldn't be any different.
As parents, we do all kinds of things to keep out kids safe. Carseats, cupboard locks, bike helmets, life jackets......the list goes on and on. Hockey parents, add neck guards to your list.
