This incident is Darcy Moore's fault completely and utterly. He decided to go to ground in a 50/50 contest in which both players were contesting a loose ground ball, thus causing the contact to be high. This is no different to a player ducking his head in a tackle to attempt to con an umpire into awarding a free kick. Furthermore, the sliding in action should clearly have been paid as a free kick to Kozzie for contact below the knees. What Moore did was the epitome of an illegal below the knee contact action, which was rightly outlawed all those years ago to prevent horrific lower leg injuries from occuring. Kozzie is lucky he didn't have his ankles snapped.
If Kozzie doesn't get exonerated for this, that'll be the final straw for my interest in AFL.
