The umpire obviously saw the backman holding. Forward in best position to take mark, backman out of position,takes eyes off ball to engage the forward. Forward thinks If we start wresting here I’m a shoe in for a free...Wrestling ensues backman gets pinged... happens all the time. The umpire may have got it wrong but it’s pretty easy to see why he called it the way he did.
As for them 25 frees you got in the goal square against Richmond to our 9.. well I don’t know what was going on there. They were probably just cheating that day.
