A pro-style offense is a broad term in American football that means any offensive scheme that resembles those predominantly used at the professional level of play in the NFL, in contrast to those typically used at the collegiate or high school level. Pro-style offenses are only run by a few college teams and virtually never run at the high school level. The term should not be confused with a pro set, which is a specific formation that is used by some offenses at the professional level.
Generally, pro-style offenses are more complex than typical college or high school offenses. They are balanced, requiring offensive lines that are adept at both pass and run blocking, quarterbacks with good decision-making abilities, and running backs who are capable of running between the tackles. Offenses that fall under the pro-style category include the West Coast offense, the Air Coryell offense, and the Erhardt-Perkins offensive system.
