SLOTTER The Erhardt-Perkins system: Developed in the 1970s by two assistant coaches with the New England Patriots, this system uses single-word concepts rather than assigning roles to each player. Nevertheless, many defensive strategies have been developed over the years that coaches use as a framework for their general defense, making specific adjustments based on their players' capabilities and the opponent they are facing. In rare instances when a seventh defensive back is inserted, it is known as a "quarter" package (5 CB, 1 SS, 1 FS or 4 CB, 2 SS, 1 FS). A squib kick is generally used to avoid a long return, although this outcome is not guaranteed. Onside kick: This is a very short kick aimed at allowing the kicking team to recover possession after kicking the ball ten or more yards. The "no punting" strategy forgoes punting altogether and instead attempts to convert on as many fourth downs as possible.|TVRI (Saluran Televisi)
