Most of the elite college football programs in America have clear identities which often include ties to a particular position on the field, even if these associations sometimes have more to do with our collective memory than recent history. USC, for example, will always be Tailback U, no matter how many quarterbacks and linebackers they send to the NFL, and Penn State remains synonymous with linebackers, not pedophiles.
It's no different with Cardinal football. Long before this current era of excellence, the generally mediocre Stanford football program would occasionally produce a great team that might find its way to a Rose Bowl, but postseason games were not the regular events that they are today. Even so, the Farm became known as fertile ground for producing quarterbacks, with Jim Plunkett winning the Heisman Trophy in 1971, and other luminaries such as John Brodie, Guy Benjamin, and John Elway* going on to become fixtures in the NFL. The Stanford arrival of Andrew Luck** ten years ago and his subsequent All-Pro NFL career only added to this legacy.
