I think he replaced it with the rule where if a ball carrier ducks into a tackle the defender must instantly adjust their whole body so as not to catch them slightly high, or else he will be sent off and treated like a criminal for the rest of his career. That rule.
Exactly tBRV , that has become so common place now , players ducking their heads as they are about to be tackled . Not blaming them for their self preservation , but by the same token , if players were tackling around the legs ( as they once did many years ago ) then the incidents of concussions would be much , much lower .
The NRL would have a much cleaner game , the clubs a lower injury count , the only problem is to convince the coaches to stop implementing all of those illegal tactics that is par for course nowadays .
On the other hand , they could get rid of the one individual who is responsible for bringing them to the game in the first place .
