In 1961, primarily using the shotgun, the 49ers got off to a fast 4–1 start, including two shutouts in back-to-back weeks. In their sixth game they faced the Chicago Bears, who by moving players closer to the line of scrimmage and rushing the quarterback, were able to defeat the shotgun and in fact shut out the 49ers, 31–0. Though the 49ers went only 3–5–1 the rest of the way, the shotgun eventually became a component of most team's offenses and is a formation used by football teams at all levels.
