Was the Payton Vilma talk just a smokescreen?

In order to be an offensive coordinator, you certainly will know about all the defenses (looks), because that's what you are gameplanning against from week to week. Payton probably assists the D-Cord with the D gameplan, looks at a little offensive film, but there is no way he is studying the opposing teams offensive snap's film like he is their defensive films. Payton may not be able to coach the defensive positions, but he I am positive he knows defenses and what each role player does in said defense.
