If the unblocked end on the running back's side (who, in a sense, is being veered) moves up the field towards the crossing running back, the quarterback pulls the ball from the running back and sprints by the end.
If the unobstructed end on the running back's side (who, in a sense, is being deflected) advances up the field towards the crossing running back, the quarterback takes the ball from the running back and dashes past the end.
