No it wasnt. Thats got nothing to do with it. A head high is a head high,hitting the head is illegal and banned already. The shoulder charge was banned for the mountains of evidence that it causes brain damage.
“The NRL banned the shoulder charge after evidence showed the average G-force from one is 10.682 compared to 6.056 from the conventional front-on tackle.
Overall, shoulder charges are 76 per cent greater in impact than the conventional front-on tackle.”
And for me shoulder charges are piss weak.. you want to hit a bloke a bloke as a sign of toughness? Do it front on and under the ribs. Shoulder charges are almost always from the side, where the player you hit doesnt see you, and they are no risk to the defender. Its about as tough as a cowards punch.
