US Patent 7896757 Football center training aid

A football center training aid comprises a box-like training device in the form of a framework, covered on its top and sides with open-mesh netting, which provides a guide to encourage accurate passing of a football by a center to a place-kick holder or quarterback, and which allows observation by a coach or trainer of the passing action of the center. The device encourages the preferred distance and alignment of the center in relation to the place-kick holder or quarterback. The device is readily portable, and may optionally be adjustable in both height and length to adapt the dimensions to players of differing ages, sizes, and to differing training objectives. The device allows the complete actions of passing the football by a center and catching by a place-kick holder or quarterback, and complete observation of the action, so that a complete and realistic assessment of the effectiveness of the passing action may be made by the coach or trainer, and corrective actions immediately taken and assessed.
