Next time you watch this offense, count how man times Garrett runs play-action, especially in the first 3 quarters... It is astonishing that Garrett doesn't run play-action to make safeties bite... Safeties just sit back all day, not worried about the run...
A timing-based offense is predicated on an effective play-action... We have none... plus, we don't really have any timing... this offense is predicated on Romo keeping plays alive with his feet, long enough for a WR to get behind the CB to chuck it... When you take away that with safety help over the top, this offense goes into the tank...
Romo is accurate at short-range, and Garrett doesn't exploit that...
