A person comments "I wish this was an easy issue to take a side on, but it's not. As much as I agree that it's important for kids to learn how to take a hit early in their playing experience, I also can't help but take into account, as the article has stated, that the size difference can be pretty drastic at that age.
I think it also needs to be taken account that minor hockey, at the grassroots level, is often taught by unqualified, but well-meaning, parents who often know nothing about the game at the fundamental level, except for maybe what they've seen on TV or what they were taught X amount of years ago. Combine that with inexperienced players and it becomes a bit of a perfect storm for serious injury."
I think players should learn younger, when the size difference isn't so drastic. I broke a collar bone in my first game of contact hockey. I didn't know how to take the hit. I would have known if I'd learned younger at a younger age. An age where players just bounce into each other and fall, not mow each other down.
Replying to this comment, coaches are required to take a training course before they can even get on the ice to help coach a team. What's the point of the training course if this is going to be used as an excuse for removing contact from the game?
