Talking about this with dh and ds - on the way back from ds(17)'s very wet and cold rugby game
and we were all unanimous that rugby should very definitely not be compulsory, ever. The slightest hesitation can put you more at risk in a tackle.
Ds is a very good scrum half (as was dh don't know if he was as good
) so is never in the scrum, but us frequently involved in the breakdown. But as he himself says, even though he is small compared to the other players, he has good technique, is confident and can tackle well. Someone else small and nervous would be at risk.
The other important thing is that all youth teams should follow the full concussion protocols. In Scotland, that now means 23 days before a U18 can play after a concussion (longer if symptoms recur) - and if there is a 2nd concussion within 12 months, the player should be assessed by a medical professional specialising in concussion.
