The safety position is a defensive position in football on the defense). Safeties are defensive backs who line up ten to fifteen yards from the line of scrimmage). There are two variations of the position: the free safety and the strong safety). The free safety tends to watch the play unfold and follow the ball as well as be the "defensive quarterback" of the backfield). The free safety is typically assigned to the quarterback in man coverage, but as the quarterback usually remains in the pocket, the free safety is "free" to double cover another player). The strong safety usually concentrates on stopping the run and covering the tight end, which means bigger and stronger players are more suited to this role. The safety position is responsible for covering the deepest part of the field and is the defenses last line of defense. Their duties depend on the defensive scheme, but their primary responsibility is to not let the ball carrier get past them. The safety position is used by primarily every team in professional football, and it’s the safetys duty to make sure every defensive back is on the same page on both running plays and passing plays. Typically if a long touchdown is scored (any scoring play), it’s the fault of the safeties.
