ABSTRACT:
Offensive football formations at the beginning of plays can be accurately drawn on paper by the use of a unitary flat template having an array of apertures therein representative of all usual offensive players in their correct positions. By using a writing instrument in selected apertures, various offensive formations can be drawn with eleven players properly positioned to start offensive plays. Upon removal of the stencil from the paper, the execution of plays to completion can be conveniently diagramed. The device is ideal for use in the construction of team playbooks.
