The Oakland Raiders' 2014 coaching staff will look a lot like the 2013 coaching staff.

The Raiders have retained offensive coordinator Greg Olson, defensive coordinator Jason Tarver and special-teams coordinator Bobby April.

They also held onto quarterbacks coach John DeFilippo, receivers coach Ted Gilmore, strength coach John Grieco, quality control-offense Justin Griffith, Quality Control, tight ends coach Mark Hutson, linebackers coach Bob Sanders, quality control- defense Eric Sanders, senior offensive assistant Al Saunders, running backs coach, Kelly Skipper, assistant head coach-offensive line Tony Sparano and defensive line coach Terrell Williams
