Luck's legs add to his value.
They also stir the numbers.
Today's article of the day comes from Chase Stuart writing for the New York Times, who once again points out that Luck and Griffin are playing completely different styles of football.
While RGIII dominates the traditional stats, Luck edges him out in metrics like QBR, which try to take a more holistic view of quarterback value. This is a classic example of how statistics don't lie, but sometimes you have to work hard to find the right stats.
Stuart does an excellent job tracing just how vertical the Indianapolis offense has been and how little help Luck has received from backs and wideouts.
There's no point in trying to discredit Griffin's play, which has been beyond superlative, but simply slapping up a passer rating and declaring him the run-away winner in a mythical race would be foolish.
The only relevant question is which quarterback will develop into the better pro in the long run, and there's plenty of evidence that what Indianapolis is doing with Luck will well-situate him for running a dynamic offense, just as soon as they find other players who can play that style.
Luck's value has been subtle, but the effects on the field are obvious. No sane analyst would cite "quarterback wins" as a valid metric, but the fact is that the Colts have possibly less raw talent than any team in football, yet stand 3-3 with wins over the Minnesota Vikings and Green Bay Packers.
There's little question that were Griffin on the Colts, his numbers would not be nearly as pristine as they are with the Redskins.
