I think regarding high tackles it’s important to understand where WR (World Rugby) are coming from: whilst we may think current interpretation is “ruining the game”, it is nothing compared to what a lawsuit by 100s of players with early onset dementia will do the game. WR (World Rugby) need to try and reduce big head knocks, or be seen to, so they are covering themselves. (Though obviously as experts say the accumulation of lots of small head knocks is probably what does it, and the solution is what Harlequins do and have basically no heavy contact at training)
