The Oakland Raiders chose a coordinator to get their offense back to a power-running scheme suited to star back Darren McFadden. The Raiders hired former Jacksonville quarterbacks coach Greg Olson as their new offensive coordinator on Saturday to revive a unit that had its worst production on the ground since 2005. Coach Dennis Allen interviewed a number of candidates, including Norv Turner and Marc Trestman, before settling on Olson to replace the fired Greg Knapp. The shift in philosophies from last season's offense is a clear acknowledgment that McFadden was not suited to a zone running scheme.
