I don't know. I mean, to me, its just basic. Everyone has it. A well called/timed screen is demoralizing to a blitzing defense. Look how effective the Saints were with it using Sproles. I get that maybe Gore isn't the #1 option but we have Hunter and soon LMJ.
It's "Constraint Theory"- that is making the defense have to think about everything, vertical/horizontal stuff, screens, draws, traps, sweeps, slants, double moves, with the idea that even the best defense can't defend everything at once with any particular play call or scheme
