Surely injury can't make something not-perfect in a contact sport? If the aim is to not hurt people and you hurt someone, then it would be imperfect. But if the aim is to say, take a mark without fumbling the ball, and in the process someone's injured in the contest, that mark doesn't become any less good.
I don't see how a tackle becomes more or less perfect based on the result. It was perfect insofar that is how people get taught to lay tackles from junior footy onwards.
He could have done something differently, but probably not without improperly doing the job he's paid to do.
Exactly my thoughts. Yes, it's terrible that Ben Brown got injured, and it's not something you ever want to see happen in a game of footy, but that doesn't mean the tackle wasn't performed well.
When you're taught to tackle, you are taught to pin the arms so that the opponent can't legally dispose of the ball. If Grundy hadn't pinned the arms, Brown would have disposed of the ball and North may have been away. Therefore, it is his job (and it is what every footballer is taught) to pin the arms.
I also personally don't think you can class this tackle as a 'sling tackle'. Brown is 100+kg - to tackle him successfully, it's going to take quite a bit of force. Grundy didn't fling him around his body, he just took him to ground in the tackle - which again, is something that you are taught to do from junior football onwards.
Either the rules need to change so that that type of tackle is illegal, or it needs to be accepted that injuries will happen and the tackle can still be legal. Because at the moment I personally think it's not good to see blokes being rubbed for tackling in the way that you are taught to tackle from U/10's upwards.
