As money managers are fond of reminding us, past returns are no guarantee of future returns. Same goes for coaches, football and otherwise.

But if Steve Fairchild’s most recent nine seasons as an offensive coordinator are any indicator, and if Virginia can develop and recruit talent to play his diverse attack, then the Cavaliers’ offense should thrive under his direction.

Virginia announced the 54-year-old Fairchild as its offensive coordinator Wednesday, one day after making Bill Lazor’s exit to the Philadelphia Eagles official.

Fairchild was available because he was part of the San Diego Chargers staff fired along with coach Norv Turner this offseason. His four seasons as head coach at Colorado State, his alma mater, were trying as the Rams went 16-33 from 2008-11 and struggled on both sides of the ball.

But in Fairchild’s four seasons as offensive coordinator, 1997-2000, Colorado State ranked among the nation’s top 40 in scoring every year, a level Virginia hasn’t reached since 2004. The Rams ranked as high as 13th nationally in rushing, as high as 28th in passing, showing balance and the ability to adjust to personnel.

Not coincidentally, Colorado State won at least eight games in each of those seasons and cracked the Associated Press final top 25 twice.

Fairchild’s most notable group was in 1997, when Kevin McDougal and Damon Washington rushed for more than 1,100 yards each, while quarterback Moses Moreno threw for 2,252 yards and 20 touchdowns.

In three seasons as the St. Louis Rams’ coordinator, 2003-05, Fairchild was part of two playoff teams. The Rams ranked among the NFL’s top-five passing offenses each year and among the top-10 total offenses.

Those squads featured quarterback Marc Bulger, running back Marshall Faulk and receivers Isaac Bruce and Torry Holt.

Not surprisingly, Fairchild was far less effective as the Buffalo Bills’ offensive coordinator in 2006 and ’07. The Bills’ personnel included quarterbacks J.P. Losman and Trent Edwards, running backs Willis McGahee and Marshawn Lynch, and receiver Lee Evans.

Below are charts on Fairchild’s seasons as coordinator at Colorado State, the St. Louis Rams and Buffalo Bills. The Colorado State chart shows its rankings among 120-plus Division I-A teams. The NFL rankings are among 32 teams.
