Abstract: In one embodiment, a method for rendering a diagram representing a football game between two teams involves rendering a plurality of symbols on a display and/or a substrate of a printing device. According to the method, in response to information input to a processor regarding at least two plays in a drive by one of the two teams, the plurality of symbols are rendered on the display and/or the substrate of the printing device along a path representing at least a portion of the drive by the one of the two teams. The plurality of symbols represent the at least two plays such that each of the at least two plays can be distinguished from the other of the at least two plays. In another embodiment, a method for rendering a diagram representing a football game between two teams involves rendering a single representation of a football field on which the game was played on a display and/or a substrate of a printing device.
