Don't go near the head. Simple. It's been let go for years, simply because it happens on a footy field. The game has survived the end of the biff, shoulder charges, and it will survive this.
Interesting, for years attacking the head/neck of a player was deemed unaceptable and worthy of penalty/sending off/sin, binning and people are complaining when referees are policing these rules. Should of happened decades ago.
Some people are suggesting that these rules will/should be relaxed for state of origin, tests etc.
Its like 'attacking a player when he has his feet off the ground taking the ball in the air', that's when he is most vulnerable, when even a slight push could result in him pitching to the ground and breaking his neck or banging his skull on the ground and his brain turns to mush, maybe not noticeable not apparent till ten years later.
That's what the Velandy (?) and the NRL are trying to change, they don't have a choice because insurance companies will refuse to meet the enormous costs involved in injury claims that are going to be lodged. Count on it.
Commentators like Gould refuse to grasp these minor facts, what a f**kwit. 'Oh thats only a slight tap, not worthy of a penalty', a slight tap when a guy's got both feet off the ground can have an enormous impact.
Glimpsed an interesting thing on the tv as I rushed out the door, this morning. Somebody was presenting statistics about injuries sustained by players who were defending, that is moving in to make a tackle and received an elbow to the head/face/throat area.
Didn't see much cos I was in a hurry but, we have all seen it, we have watched an attacking player (Weereea Hargraves is a specialist at it) slam a defender with an upraised forearm and charge on.
I think this is an area of the game that needs more policing and cleaning up.
