Intentional grounding regards the quarterback; there is no one in the vicinity of his throw and he is within the tackle box. If the quarterback gets outside the tackle box, as long as he throws the ball to the line of scrimmage, it is not considered intentional grounding but if the quarterback is inside the tackle box and he is trying to avoid a sack so he throws the ball away, and there is no one in a 10 yard vicinity of that area, it is considered intentional grounding.
