Single-wing formation

In American and Canadian football, a single-wing formation, created by Glenn "Pop" Warner, was a precursor to the modern spread or shotgun formation. The term usually connotes formations in which the snap is tossed rather than handed—formations with one wingback and a handed snap are commonly called "wing T" or "winged T". The single wing was superior to the T formation in its ability to get an extra eligible receiver down field.
