Speed option - QB coaching points

This is how they did it at Nebraska:

Under Center
Open at quarter step
Come with speed out and around the corner
Attack the outside shoulder of the force defender (will either be safety or corner)
Option off force defender

Shotgun
Run down field attacking the outside shoulder of the defensive end
Option off defensive end

Why to attack the outside shoulder
It cuts down the angle the defender has at batting the ball.
When the I-back catches the pitch they wanted him 2-3 yards from the line of scrimmage with shoulders parallel to the LOS.
The defensive end cannot play both the quarterback and I-back.

Landmarks used in the option game
If lined up on left hash and running to the right or wide side of the field the quarterback has until the other hash to make the pitch or turn it up field.

If lined up in the middle of the field the pitch must be made by the numbers.

If lined up on the left hash and running to the hash or short side of the field the quarterback again has until the numbers to make the pitch.
