You missed the point. Perhaps the rules are flawed. Wouldn't be the first time.
That's a different issue. Maybe they are. But they've been the same for a few years now - ever since the AFL decided to protect the head - so claims that this decision changes the game are simply hyperbole.
I think that the decision that really did confuse the issue was the one to let Maxwell off for his hit on McGinnity a few years back. The AFL were heading down a clear path - protecting the head - when that decision confused everyone.
