To give a small bit of credit to the umps and the rules committee, one of the positive changes over the last few years has been the reinterpretation of the high contact rule. Now if you you shrug, duck, or lead with your head, you're just as likely to get pinged for holding the ball as draw a high contact penalty.
Because keep in mind, that's what Selwood does. He doesn't 'go lower, and harder' or whatever nonsense Geelong supporters like to spout, he has a technique for slamming his neck into opposition forearms. A little bend of the knee, a little flick of the shoulder, and that last second acceleration into the tackle.
What always annoyed me is that this is a meta-skill. It's not really footballing ability, it's a manoeuvre that exploits a loophole. Which has thankfully been made much tighter.
Selwood has always been an average skilled footballer, with no regard for personal safety, a winners mindset, and effective trick. And he's showing his limitations now they've pointed out his trick was essentially cheating.
Though it does make me laugh when all the Geelong supporters who are so used to getting things their own way start losing a couple of games and blaming the umpires for not giving them preferential treatment.
