Leave the umpires umpire, if they see it as an illegal tactic then award a free kick against the tagger, you can not blame the tagger if they get away with the niggle off the ball. If they all off a sudden what to get rid of the niggle then adjudicate on it, the coaches and players will adapt, they are used to it with the amount of rule changes and interpretation changes that occur in the AFL. There wouldn't be a sport on the planet that changes rules/interpretations anywhere near the amount that we do.
I did say in our review thread that I had zero problem with what Nick did but with 24 hours to cool down and think about it IMO Nick got caught up in the emotion of the game there for a while which I find understandable and eminently forgivable. Nick plays on the line which I love, he is occasionally going to fall slightly over it, we have to accept that if that is how we want him to play. I would be very surprised if he got suspended for the headbutt due to the impact being very low.
