To move the ball with the Dropback Pass, we like to clear up the Quarterback reads by using motion. In this case, we use Whirley Motion on the Stretch Pass. The QB reads the FS. If the FS moves with Motion, the QB treats it like a 3 Shell & go back side. He reads the OLB & throws to the WR unless the OLB gets under the out, then he checks down to the Whirley Slot.
