I've not seen the Wakefield one, but they might have a point on the Hull one. He very deliberately aims the shoulder high on the Hull player and it is very dangerous contact. If it's banned for the tackler, I don't see how it's any safer for the ball carrier to do it. I'd suggest un-banning the shoulder charge for the tackler as well, but make it so shoulder contact with the head is a minimum 12 game ban.
