I think the problem is that the NRL have had medical advice that states shoulder charges are a dangerous, high risk "tackling" method. To ignore that advice would make them liable should anything go wrong. By allowing that tackling technique you are accepting the risk and therefore condoning any potentially bad outcomes.
Let's face it, the whole idea of a shoulder charge is to cause maximum damage or intimidation. It's not what you would call a high percentage defensive play in terms of KPI in stopping the runner or the offload. Invariably the most successful ones are where the recipient is "blind sided" and not braced for contact, or they are out and out cheap shots like Inglis put on Dean Young (players back turned held by another defender).
I can see why the NRL wants to ban them, they are just too risky in terms of potentially bad outcomes because there is very little control by the tackler. If they were all like the Evans v Kasiano version then fine, there would be a place for them in the game. The fact however is that they are not all like that and are too much of a liability for the administrators to carry. Much the same reason any contact with the head is outlawed, or would people rather we go back to the good old days when no forward had a straight nose and all their own teeth ??
