Pre-snap motion is designed to be one of an offense’s biggest assets. It can determine the type of coverage a defense plays between man or zone. It can create favorable matchups and strong leverages across the formation. Most importantly, it offers variance to give quarterbacks high-percentage looks and creatively utilize playmakers to produce explosive plays in the air. It also can provide angles to create personnel advantages on the ground.
Every team uses motion to some extent. Some use it with a structured plan to keep defenses guessing and attack them while they search for answers. Some use it aimlessly without reaping any real benefits from it.
