West Coast Offense

Verified Timeline

Lore & Background

The origins of the offensive system devised by Walsh go back to Paul Brown, coach of the Cleveland Browns and later the Cincinnati Bengals. Under Brown's tenure, Walsh was tasked with devising an offensive plan suited to Bengal quarterback Virgil Carter, who had an accurate but relatively weak arm. In response, Walsh created a system based on short, high-percentage passes, favoring straight and direct ten- to fifteen-yard strikes over forty- to fifty-yard "bombs" - the very opposite of the thrust of the long pass oriented later Air Coryell system. This system compensated for any weakness in the quarterback's arm, as it allowed the ball to be thrown to short and intermediate routes where receivers with running ability could attempt to make up for any shortage in yards after catch. Walsh's system immediately paid off, as Virgil Carter led the league in passing percentage in 1971. Strong-armed Ken Anderson, initially a "project" of Walsh's, replaced Carter as Cincinnati's starting quarterback in 1972 and was even more successful in his execution of Walsh's complicated, versatile patterns, leading the Bengals to a division title in his first year as starting quarterback. In 1975, he brought widespread recognition to the West Coast offense in a nationally televised Monday-night contest between the Bengals and the Buffalo Bills, whose offense was built around league-leading rusher O. J. Simpson. Anderson's 447 passing yards were enough to overshadow Simpson's 197 yards on the ground in a Bengals win that proved a milestone, providing a striking contrast between the "old" ground game of defense-oriented football and the new game envisioned by Walsh—a game of higher scores, more action, and much air travel.

In Their Own Story

At the end of the 1975 season, Bengals head coach Paul Brown would retire, and he appointed Bill Johnson as his successor instead of Walsh. Ambitious and anxious to become a head coach, Walsh resigned from the Bengals and left Cincinnati for the West Coast, taking along his films of Ken Anderson running his offensive schemes to serve as a teaching aid for quarterback Dan Fouts after Walsh had been hired as an assistant coach for the San Diego Chargers. Next, after two years of success as head coach at Stanford University, Walsh received and accepted the call to be head coach of the San Francisco 49ers. He would soon transform the 49ers from a mediocre team to a perennial league powerhouse, recalling the dominance of Vince Lombardi's Green Bay Packer teams of the 1960s, and of Chuck Noll's Pittsburgh Steelers of the 1970s. His versatile offensive schemes, along with his high percentage passing game and emphasis on ball control, complemented the skills of Joe Montana, who implemented Walsh's visionary system with great success as the 49ers' starting quarterback. Walsh's 49ers won three Super Bowls during this period, behind the passing abilities of legendary quarterback Joe Montana. Besides the 3 Super Bowl wins, Walsh won 6 NFC West division titles and compiled a 92–59–1 regular season record, with a 10–4 mark in the NFL playoffs. Montana captured 4 Super Bowl titles (three of them under Walsh), 3 Super Bowl MVP awards, and 2 AP NFL MVP titles while in San Francisco in the 1980s. Montana and Walsh have both been inducted into the Pro Football Hall of Fame.
