No one can prove it one way or other except those with inside knowledge of the code. My opinion is based on playing thousands of games and seeing the results play out on the field. It's not the results of the plays like say, 70 yd touchdown pass. It's the way it plays out, like for example two deep zones in a cover 4 standing still and letting someone run right by the them without reacting when there's no other wr in the area.
