Quote: Him "Accidents I'll accept. Trained techniques I won't.'"
Nail on the head; and I share your suspicion of coaches and players. There is a mountain of evidence that tackle techniques are constantly evolving to 'win' the ruck, and the latest incarnation is the first man in going high and holding the attacker up, so that others can join one by one and chop him to pieces, turning him over in the process so he ends up on his back, with his head towards his own sticks - they then peel off one by one, which takes the longest possible time. That's considered a defensive 'win' from a coaching perspective, but I'm sure it's not what the rules intended.
I'm not at all in favour of removing collision or risk from the game - but I am in favour of removing the ability of coaches to play fast and loose with the rules to the detriment of player welfare and the spectacle.
