Sorry, you've lost me here. Do you understand what the judiciary is for? If you are banned for two weeks for striking the head of a player, why is that not a sending off offence? It has been deemed an illegal action worthy of two weeks suspension. The same for Masoe. He has hit a players head. It is illegal play and deemed worthy of suspension after review. They both should have been sent off in accordance with the NRL's own rules. I didn't make the rules, but they are clear.
You are arguing about the whether the rules are appropriate. Now, it is a different argument to say whether the actions should be punished with a suspension. I never said the punishment fits the crime. I think you are arguing about whether the league should award suspensions for tackles like that. "they've gone soft" seems to be the opinion of many.
However, if the rules state that the tackles are illegal (section 15 of the Laws Of The Game - recklessly striking the head of an opponent) and two week suspensions are appropriate then they are sending off offences under the current rules (section 16 sub section 6 - power to dismiss).
For the record, I think leading with the knee, as Kade did, should be illegal and should be punished. It will result in someone getting badly hurt. At the very least concussion is likely and there is massive medical evidence to show that concussion can lead to brain damage. Google "nfl head injuries" and read the reports. If you are an official in the NRL or at a club, ignore this at your peril.
I think a better way to interpret the rule would have been to award a penalty and if the player is unable to continue as a result of foul play, the offender also sits out the game. On review, if it is deemed worthy of suspension then the fact the player has already sat out the game is taken into account and the sentence reduced accordingly.
