First, that blue line is the flight path of the ball. Also, I know people will complain that they saved shots that were counted as goals. You are not viewing it in 3D. If the ball is in front of the goal and you are in front of the goal, it is not a goal yet. If you stay there, it will be a save. However if you move out of the way, IT WILL BE COUNTED AS A GOAL AS IT SHOULD BE.
Thanks to 123RF for the goal image
