The fact remains, more people are injured or killed in other sports or means of recreation (swimming, rock climbing etc). It is a risk that can be minimised but never ruled out altogether. It is part and parcel of a physical contact sport and people who participate in it are aware of the risks. You will notice though that I have advocated a ban on shoulder charges during junior development and made provisos for their regulation (not near the head, not from behind or after the player is no longer in possession of the ball and if there is separation (which I am aware is no longer the rule). I would rather follow another sport altogether than see the game I love diminished even further into an alternate version of Oztag.
Some Mothers and Fathers think if their boy/girl plays League and some Islanders kids are much larger, they automatically say "we don't have our kids playing League" It's a lot better than when I played in junior levels.
It's a contact sport what you wrote - it's not Oztag.
