If the judiciary is going to be consistent then most of the best tackles are illegal
For example see https://www.youtube.com/watch?v=ZNT2hIaiGmM
Many of which are exactly the same as Evans
Evans was told that he chose a high risk tackle when other options were available. That means he should not have made that style of tackle. Since other options are always available and a risky/dangerous tackle is illegal regardless of whether the player gets hurt or not, it is a logical conclusion that most of the greatest tackles this year and other years are grade two careless tackles and the tackler should be sinned binned and suspended. Also Evans tackles are in plain view on a player who is looking ahead. Tafuas are usually suprise attacks so evan more dangerous.
NRL must now be consistent and all these dangerous tackles must get grade two charges.
There is no way Evans can know if the player will brace or fall into his tackle head first. So it is the choice of making this type of tackle that is wrong. It is a dangerous tackle and must be treated like a shoulder charge. Be consistent NRL an ban your own game.
