We’ve heard for the last several years that running back doesn’t matter.
Mike Shanahan basically made the need to draft, develop and re-sign backs something of an anomaly because of his ability to pull 1,000 yard seasons out of bodies in the late round and undrafted free agents.
His son continues in his ways with a trio of unheralded running backs all producing at a high rate.
The Arizona Cardinals under Steve Keim looked to be following that method.
In 2013 they signed Rashard Mendenhall to be the lead back at the cost of pennies and drafted Andre Ellington and Stepfan Taylor.
