I typed the previous comment without seeing this. Yes, a definite possibility that the drive stalls and the Saints get the ball back with 5 minutes or 1 minute on the clock, but in either situation, you are then giving the ball over to the Saints, who can then ice the game. If I am the coach and my team is down by less than 8, I am looking at that final drive as having the game in my hands. So I am going to do whatever I can to make sure that the opposing team has very little, if any time on the clock, if the ball is turned over. No different then what you see teams do when a FG will win the game, you take the clock down to 1 second and put your faith in the kicking unit to get you the win.
