You don't get it. It's a designed quick-hitting play. Cooks role inside was to carry the Safety with him, thus allowing CeeDee to be wide open on that twins-set, double left, quick slant play. The problem like Kurt Warner said is it was horribly designed by having both Cooks and CeeDee run the same depth (5 yards) before both slanting inside. That allowed the Safety to step up in between both and cover both, thus the pick-6. Also, the play-action should have never been included in the play since all it did was cause Dak to be late on a pass that has to come out quickly. Kurt Warner clearly talked about both big no-no's on that play. THAT is on the coaching staff for a poorly designed play.
