By running a hook on the outside with a slant coming underneath towards the sideline, you are isolating the safety, and forcing him to come up and bite on the hook, leaving the slant uncovered, or sitting back and allowing the completion underneath.
Set up a series of garbage cans and pylons in the positions the defenders would be standing.
- Have your receivers line up on one side of the field.
- Have two quarterbacks line up under center.
- Designate which quarterback is throwing to which receiver, and then have them drop back and each hit their men in stride.
With the middle of the field, the deep ball, and the flats pretty well covered, there are soft spots along the sideline at around 8-10 yards.
