A System quarterback is an American football quarterback who flourishes under a particular offensive system, specifically one that focuses on passing. The term is often seen as derogatory manner, as it implicitly downplays a quarterback's talent or skill by implying that a successful offense is due to a particular scheme or that a quarterback is successful due to his employment under specific circumstances. A system quarterback is usually perceived as having their statistics inflated by a particular strategy. Offensive schemes that tend to feature so-called system quarterbacks are the "run and shoot", spread, and, less frequently, spread option offenses.
