but he is still staring down receivers, not going through his progressions, and his vision is suspect.
if you can make the play with your primary receiver, you don't need to go through your progressions. Most of your "progressions" are done at the line of scrimmage anyway. You should be able to predict which routes have the best probability of being open based on the defense. The QB does not drop back, progress through all the routes to see who's open then decide where to throw the ball. Typically what looks like "staring down" is when the QB's primary target is one on one and he knows he's going to make that throw regardless.
