The middle receiver, runs a spot route, while the outer most receivers runs some type of hook route. In this playbook, there are two primary types of protection. The West Coast Offense has a simplified play action pass protection system to easily incorporate run fakes on almost any play. The Double Dig has two receivers running dig routes to the same side of the field. Bill Walsh, who was the offensive coordinator at the time, had to step back and completely redesign the teams offense. Run Passes: If a run is called with pass tagged onto it, like 16 power pass, or 19 BOB pass, the offense executes the running play, but blockers do not go downfield so that a pass can be thrown. an off set back is going to get the . This is similar to the idea of "concepts" in the West Coast Offense, except the West Coast terminology sometimes names plays after the primary receiver's route, like "Y Spot". The Curl Flat route combo has the outside receiver running a curl, while inside receiver runs a flat route. If the defender covers the hitch, the deep in route will be open. The Levels concept does an excellent job at attacking zone coverage. The Slant is a short timing route that has the receiver breaking towards the middle of the field for a quick pass from the quarterback. This real football play passing concept features a high-low read between a receiver, who runs a post , and a running back, who runs an angle route. Walsh used a traditional hole-numbering system: Evens right, odds left. For West Coast teams that love to use quick-hitting pass plays to move the chains, the POP play is a God-send for how it integrates what that team has to spend practice time on. It can be ran from three, two, or one-back formations. On 300, the slide goes away from the call. Any play with a 1 in front of it (making it a triple digit play starting with 100) means the QB takes a 3-step drop. Bill Walsh helped changed the offensive playing field with his West Coast offensive system. If youre a fan of the NFL, youve probably heard the term West Coast Offense. You have also probably seen or heard NFL content where a coach or player says an incredibly long play-name that sounds like a language only C-3PO could translate.
