Fantasy footballers want all the information possible to help determine the stock of running backs. After all, chances are you'll be investing your first-round pick in the position. Whether it's trends, depth-chart movement or personnel changes, there are a number of different components that can impact a runner's value.
An effective quarterback isn't one of them.
Sure, Edgerrin James benefitted from the presence of Peyton Manning during his time in Indianapolis, and life was much easier for Emmitt Smith in Dallas with Troy Aikman under center. But the absence of a reliable signal-caller is no reason to pass on an otherwise talented back. The proof of this statement is evident when looking back at some of the most productive seasons at the position during the Super Bowl era.
