I’m sure I’m not alone here, but I started playing rugby in 1974, and I have seen many, many law changes. Many of them quite considerable, and I do recall plenty of doom-mongers predicting the death of the game over the years.
I don’t believe we will end up ‘below the waist’ but even if we did I would be quite happy to carry on, as I know Rugby will survive.
I referee quite a lot of Colts and U16 games and rarely am I picking up high, or dangerous tackles, even when the testosterone and teenage anger is flowing at its mightiest.
The real problem is with this very small (in the history of the game) group of players between say 20 and 35 ish who have never known a time when tackling was a low thing. That is; before the advent of RL coaches at the top level which then flowed down. This is not a criticism of RL by the way.
