Quick Question about Zorn's Offense

[CRedskinsRule]

QUOTE OUT OF International Herald Tribune LINK MATTY POSTED:
"While Zorn wants to use as little of the play clock as possible, Campbell does have more freedom than he did under Gibbs. Audibles are back, although Zorn hopes his play-calling is good enough so that the number of Campbell's change-ups stays in the single digits per game. Campbell also can opt for the shotgun on certain plays. As a former quarterback himself, Zorn realizes the value in having flexibility at the line of scrimmage."

I know I have been wondering why Collins/Brennan used the shotgun so much more than Campbell did, always thought it was Zorn's decision. Does anyone know how much Campbell has used it? I am really curious
