The offense uses a specific naming system, with the routes for (wide receiver) s and tight ends receiving three digit numbers, and routes for backs having unique names. For example, a pass play in 3 digit form might be "Split Right 787 check swing, check V ''. (see Offensive Nomenclature). This provides an efficient way to communicate many different plays with minimal memorization. Conversely, the Walsh "West Coast offense '' could in theory have more freedom, since route combinations are not limited by 0 - 9 digits, but at the price of much more memorization required by the players.
