So the head isn't sacrosanct any more. I think I remember Fyfe getting 3 weeks suspension for an accidental head clash because he chose to bump. If not for that, he could have won the Brownlow that year too.
First, don't think Fyfe should have been suspended a couple of years ago but the rule was if you had an option and chose to bump, you are responsible for any consequences. Fyfe could have gone the smother or tackle, hence the penalty.
Gibson didn't have a choice as he was shepherding. He also kept very low.
Don't like Gibson much, but you're comparing apples with pears.
Did they bring in a rule about shepherding the player on the mark a couple of years ago, or was that just a Margetts interpretation, as I recall a couple of Freo players being pinged for it, Crowley was one I remember.
