I didn't know about this, but then again I am not in UK. I live in SA, so sport wise, very much pushed in schools. You can see how much of a priority is placed on the sport but the amount of bursaries given out to top private schools, just on the child's ability in rugby. The competition between the top schools and rugby is incredibly fierce.
My ds (17) started rugby in high school. This year out of the blue he announced that he is no longer going to play. I was completely shocked as he seemed to love it, never missed a practice, all his friends are boys from the team etc etc. But, he was benched last year due to 3 concussions in a row... I saw all the incidents...I wouldn't say that he had tackled incorrectly, but on each occasion the injury was caused maliciously. There is so much of it that happens in the games, the other team target one player, do what they need to, to get him out...this was usually ds because being a wing, if he got the ball, he would most definitely get the try. There is so much politics within the game too, that it actually spoils it in the end. So when it comes to selections for first/2nd team as they are in that age group now, its not which players deserve to be there...its those whose parents dig deep in their pockets to get their son there. So, with all these factors, he took the decision to stop playing. It is his decision, and I will stand by whatever he decides. His career is not going to be that he will be a Springbok one day, so in the grand scheme of things, it really isn't an issue for us at all.
But, there are boys who want to make a career of the sport and I wish them well. But the boys who I know that wish to make a career of it, are mostly heavy set, strong boys...who up until now have been fortunate enough to escape any injuries. Unfortunately not the case with ds, he is very small framed...so weight wise half the weight of the props etc. The smaller the child, the more susceptible to be injured in my opinion. Ds has had some form of injury every year since starting, including having to have surgery to replace a finger which was purposely trampled on with metal studs AFTER the ball had been passed. Again a targeting move to get him out.
I don't agree that it should be compulsory though, contact or not. Not everyone enjoys the same thing...you either like the sport or you don't.
