New Raiders OC Greg Olson said he will be emphasizing running back Darren McFadden's strengths this season, likely by instituting a power running scheme. Fired OC Greg Knapp installed a zone blocking scheme that went away from McFadden's strengths last season and the running back only gained 3.3 ypc in 12 games. SOURCE: MercuryNews.comFantasy Spin:McFadden flourished in 2011 under a power scheme, producing 614 yards and four touchdowns on the ground on 113 carries (5.4 ypc) in seven games before suffering an injury. We still believe McFadden possesses immense upside but it's doubtful he will ever play 16 games. Still, he might be able to produce third-round value even in 12 games if he is used correctly.
