I have a lot of sympathy for Walmsley. Nowhere near as bad as Moons and he was attempting a legit tackle and got int wrong.
A bit late and reckless ( because it hit full in the head)but was trying to tackle.
1 match ban for me would be fair taking into account the Sending off.
And as for the OP get your head out of your arris and smell the coffee.
Read these forums, read the papers look at issues to do with concussion in AFL, NRL, RU and even football where there is talk of banning heading the ball.
The RFL have to show that they take head injuries and concussion seriously.
The first step is to show that any attacks to the head deliberate or accidental are not acceptable and that there are consequences.
When the first SL players start suing the RFL for lack of care re concussion and head injuries there first argument will be that the RFL did not punish players or protect players from injuries in the first place.
so to the OP Attacks to the head now will be punished so get over it.
