Again, cliches. We don't go around trying to have accidents. We normally look before crossing the road. This isn't the same thing. Injuries in rugby are increasing and severity with them. If you consider the safety of young rugby players a price worth paying, and any changes designed to prevent injuries simply an example of the nanny state, I can only assume you've never saat by a phone waiting to hear if one of your young charges has a serious injury or not. You can't make an omelette without breaking eggs, eh?
Now, as to risk, of course there is a degree of risk, but we don't just wait for accidents to happen. We take steps to avoid them. Reducing risk is what has led to fewer accidents in the work place. Why not apply that to sport?
