so in essence any player with the ball cannot be tackled from behind - laying a fair tackle would mean pinning their arms in the process they lose/drop ball but wait for it - because their arms are pinned upon falling down to the ground they risk hitting their head (tacklers fault for pinning player's arms in the first place).
AFL needs to introduce new rules around this then to say no tackling from behind as not allowed due to risk to player with the ball.
