The joke is supposed fans of the sport that can't see what is being adjudicated.
We were done for 3 ruck infringements, the ones today we're 1 ruck infringement and 2 inside 10m. They aren't the same.
Similarly a ball plant is when a player puts the ball on the ground before they get to their feet. Edwards had gotten to his feet.
No doubt we got a couple dud calls yesterday when the game was in the balance. We also got piggy backed upfield by some soft calls all first half.
I don't get the ref bashing culture in our sport (or any sport). It only leads to worse refereeing standards. But if you are going to criticise anyway, first understand what you are commenting on.
