Left arm is tucked into his body, leading with shoulder for contact... That is a shoulder charge.The wording is below:
"• The contact is forceful, and;
• The player did not use, or attempt to use, his arms (including his hands) to tackle or otherwise take hold of the opposing player."
I'd argue that even if the hand makes contact, it was incidental and he did not use, nor attempt to use, his hands or arms to tackle.
The idea that someone could make a hit from side on with the left shoulder and claim that the right hand was in any way a part of the tackle just seems ridiculous to me.
The quote is 'arm (including hands)', that means arm and hand, not just hand. The arm needs to be tackling, with the hand included - essentially a wrap/grab. This is so that you can't lead with the shoulder contact and just stick your arm out straight (as that gets more impact than if you're having to include hand in a wrapping motion). The rule was brought in to reduce impact - they said it's not just attacks on the head, it's all shoulder charges because of the impact and potential to cause whiplash type brain injuries.
It's an absolute bullshit rule, and we're making the game soft. Slaters tackle should be legal, but in the current rule interpretations, it simply isn't. He led with his left shoulder, yes his right hand ends up involved, but that's more in a bracing, pushing position - when you do a shoulder charge, generally you tuck your body tight to protect yourself and also increase your impact (tight, smaller body = more velocity). Essentially, he is not using his right arm, including his hand to make a tackle, it's there as part of the shoulder charge motion with his left shoulder.
Its absolutely nailed on a shoulder charge action under the interpretations.
As I say, I believe this tackle should be legal (in any part of the field), but as it stands, it's illegal and has a mandatory ban.
It all goes back to the very fundamental reason they chose to ban the shoulder charge completely and not just for high/dangerous contact - to reduce impact levels and potential whiplash brain injuries. Games gone soft, Billy should pay the price as a result of this. If he doesn't, it is clearly favourable treatment.
