The San Francisco 49ers have been around this block on more than one occasion. For the last seven seasons actually.

Mike Martz, despite having some success with the 49er offense, was given the boot by Mike Singletary due to conflicting offensive philosophies. Then Singletary hired Jimmy Raye, a grizzled old veteran that knows a similar Coryell style digit offense that former offensive coordinator Norv Turner implemented during his one year in San Francisco.

The Coryell Offense combines deep and mid range passing and powerful inside running, an apparent must for Singletary's vision of the team. Pass protection is critical to the success of the play because at least two of the five receivers will run a deep in, skinny post, comeback, or crossing patterns that were often favored in Martz's variation of the offense.

The version that Raye learned from Turner is generally quarterback friendly and favors taking controlled chances, like quicker mid-range post passes to receivers from play action rather than Martz's version which emphasizes seven step drops and slower developing passes that can produce big plays but also leave the quarterback exposed and prone to big mistakes if the pocket collapses.


In order to run a proper version of this offense, quarterbacks need to have big arms with deep accuracy, wide receivers must be able to stretch the field with speed and separation, tight ends must be strong blockers that are heavily relied on in pass protection and the ground game while running backs need to carry a heavy load and have good power to take the constant pounding.

Turner and his associates prefer to feed the ball to a feature back like Emmitt Smith or LaDainian Tomlinson.

The San Francisco 49ers are capable of the running aspect of the scheme but they simply do not have the personnel to run the passing variant of the offense. This was quite obvious when Singletary benched the gun slinging turnover prone O' Sullivan for undrafted journeyman Shaun Hill, a quarterback not known for his big arm.

As a result of Martz having his hand picked quarterback benched, the offense was finally turned over to a good game manager in Hill. The play calling had to be toned down to accommodate Hill's strengths: intelligence and accuracy.

Suddenly the offense started to run some familiar plays from the past. Quick slant here then a quick out there and suddenly the 49er offense started to look methodical, like an old Bill Walsh team.


The reason for this sudden transformation into the "West Coast Offense" is due to the fact that Walsh's offense is a philosophy and an approach to the game rather than a strict set of plays or formations.

Bill Walsh's West Coast Offense emphasizes a short, horizontal passing attack creating player mis-matches, thus opening up running lanes. The West Coast Offense (WCO) features precisely run patterns by wide receivers that stretch the defense out. The offense is then free to focus the remaining plays on longer throws and mid to long yard rushes.

On these passing plays, the quarterback makes three reads after taking the snap from center and if no receiver is open after three reads, the quarterback will then check down to a back out in the flat or the tight end.

Another key element to Walsh's attack was the three and five step drop instead of the seven step drop. The three and five step drop helped the quarterback get the football to the receiver faster, resulting in far fewer sacks. WCO plays generally unfold quicker than Air Coryell.

Wide receivers in the WCO must have good hands and be comfortable catching balls in heavy traffic while the Coryell offense requires speedy receivers that stretch the field vertically.


WCO offenses also rely on complete running backs and fullbacks who are able to catch the ball as well as tight ends that can catch and run. Former 49er running back Roger Craig was a leading receiver out of the backfield for San Francisco on numerous occasions and in the 1985 season, good old "Cat Fish" was the first running back to be a 1,000 yard rusher and 1,000 yard receiver (Roger Craig deserves to be in the Hall of Fame, but that's another story for another day).

This versatility often had Walsh's 49ers mislabeled by the media as a "finesse" team but Bill Walsh was a former boxer in the United States armed forces and always preached to beat the other man to the punch.

Walsh knew smash mouth football and proved it on the biggest stages. Watch the 49ers' final drive of the 1982 NFC Championship game. Yes, "The Catch" happened during this game but nobody ever seems to remember former Cincinnati Bengal Lenvil Elliot running circles around the Dallas Cowboys' vaunted "Doomsday" defense on that historic drive.

Finally, the West Coast offense with its emphasis on quick reactive skills is a perfect stage for the athletic quarterback. When a defense like the Tampa-2 negates an advantage of the West Coast Offense, the quarterback that can run will pose a threat to make the first down himself, adding another dimension to the offense.

Singletary has stated on numerous occasions that he wants the type of offense that Bill Walsh used to run as head coach of the San Francisco 49ers.


Hiring Raye as offensive coordinator may seem like a stretch to many because of his coaching background, but it takes philosophy to execute a WCO style of passing offense and maybe a fullback that won two titles with the Super Bowl era 49ers.

The return of Tom Rathman as running backs coach brings back some of the WCO knowledge of the glory years. He also brings a knowledge of zone blocking schemes that were being run during his tenure as the Oakland Raiders' running backs coach.

In order to run such a zone blocking running scheme, the 49ers would need athletic offensive linemen that are always on the move. Tackle Joe Staley is the only lineman on the roster with the athleticism necessary to run such a scheme. The rest of the 49ers' offensive line are big bodied maulers, a much better fit for the power run attack.

Current personnel dictates the 2009 San Francisco 49ers' offense must utilize a bruising power run attack and pick apart pass defenses with a Walsh-like scheme based on a horizontal passing attack where the receivers' ability to run after the catch can be utilized for this team to compete.

When opposing defenses start to press at the line of scrimmage and cover the shorter routes or stacks eight men in the box, it's time for some play action Air Coryell that Raye should be well versed in by now.


Will this harmony be achieved? We'll find out September 13, 2009.
