To answer the intentional grounding question.. according to NFL.com Intentional grounding will not be called when a passer, while out of the pocket and facing an imminent loss of yardage, throws a pass that lands at or beyond the line of scrimmage, even if no offensive player(s) have a realistic chance to catch the ball (including if the ball lands out of bounds over the sideline or end line). It sounds like you need to be both out of the pocket AND the ball must go past the LOS.
