Here is an interesting 5 man dog from the Dallas Cowboys' Defensive Coordinator Rod Marinelli.
The play starts in a standard 4-3 2 high safety shell look.
During the cadence the DL stems the Nose and DE into this look.
The Nose moved to a head up zero technique and the DE went from a wide alignment to head up on the OT.
The defense then stemmed a 2nd time into this look.
The Nose moved to a strong side 1 technique and the Sam backer walked up on to the LOS. The stemming by the defense allows the Cowboys to create a odd front structure and bring a 50 front type of pressure.
Sam & End - Contain Rush
End - Inside Rush
T&N - Delayed twist
3 under 3 deep
The penetration of the Nose in the A gap forces the Center's shoulders to turn. The delay twist by the Tackle is able to loop tight and pressure the midline.
Using pre-snap stemming and DL alignments are creative ways to incorporate Odd front concepts into a base Even front defense.
