French rugby deaths an 'unusual spike', says World Rugby chief Gosper

One reason totally ignored is that in the youth categories you have huge differences in weight, height, strenght between the players with kids weighing 55 kgs and others 90.

lowering the tackle height from shoulders to waste is a must! For neck injuries.

but it will increase concussions by the tackling player either because of contact with hip or knee of the tackled player or when they fall and the tackling player is hit by the tackled player.
