Hulk's shot for Brazil during a 2-2 draw with Paraguay is the stuff of legend, and not in a good way. It makes absolutely no sense. He has a relatively open shot at goal, but instead of taking it or even passing he just struck the ball with the force of a shot -- right across the goal and into an opposing player.
Maybe this was his plan. Throw off Paraguay with a ludicrous shot as some sort of psychological warfare. It didn't work, but hey -- this is the only explanation.
