That rule really bugs me. If I remember correctly, it was brought in for players who were, say, kicking in, but because they wanted to not be under pressure, they walked the ball over the line to concede a point. Or, in the case of a player who was in the goal square, under no pressure at all, decided to walk the ball over. Sam Mitchell did this a lot. Then, he did it in one of the Hawks' GF appearances and the next thing you know, the AFL deemed it to be a bad look and changed the rules to award a free kick to the player who did this. Now, it's morphed into this thing where if you give up a point if under pressure, you get a free kick awarded against you. In the initial instance, it makes sense, but not the way it's being interpreted now.
