I'm struggling with seeing how this is legal.
If a 9 picks up the ball at the back of a ruck just behind the goal line and while diving to score over his knee or elbow catches one of the defenders on the head getting to his feet at the back of the ruck - what would you do?
Many agree that hurdling players in open play can be done on a "any contact with the boot on the hurdled player constitutes foul play" basis, so does that mean any contact from the attackers legs on any of the defenders (including those in the ex-ruck) would constitute foul play when leaping over an ex-ruck?
