The zone stretch scheme (outside zone or wide zone) has long been a favorite was for zone-based offenses to get to the outside, or at least stress the defense horizontally. Teams like Iowa have long used it as their base run play from a single back, pro-style set (often 12 personnel), while teams like Northwestern have often used it to threated defenses from a spread formation. Many other squads, including Maryland, Indiana, Penn State, OSU, Michigan, and MSU have recently had this play in their dossier. But when it is known to be the base of your rushing attack, it has fairly obvious keys that allow defenses to attack it and shut it down, either through formation or through how they attack post-snap, so at times it helps to have variants of the same play. That is where the pin and pull concept comes into play. The pin and pull concept is essentially a gap/man tag for the OL to switch to in order to attack with what is essentially the stretch scheme. Let’s take a look.
