It's been made abundantly clear that contact to the head is regarded as inherently different to contact with the body.
This is not unreasonable, in light of what we now know about the devestating consequences of concussion, something seen as trivial only 15 years ago.
But Cox did make contact to the head? You haven't answered my previous question at all? If roles were reversed and Hanrahan/Kelly end up with each other's prospective injury outcomes, do the same penalties apply, or are they flipped to reflect the severity of the result?
Astbury also made contact to Plowman's head, with his swinging intentional elbow to the head - he also received a fine too? If he had of flattened Plowman and concussed him from the very same action, does the grading then change?
There is really is no other conclusion to reach than, 'you better hope your opponent can take a punch - otherwise you're screwed'
