Whether a ball goes 15 yards in the air isn't a great measure of a "deep pass" in my opinion. The point of the deep pass is to stretch the defense out. To me, it's not a deep pass if it goes 16 yards through the air. It's a deep pass only if it's an attempt to get the ball over the safety's head. That's what we don't do often enough, and consequently we find ourselves facing cover 2 umbrellas in which the safeties are relatively shallow.
