The Raiders have hired Greg Olson as their offensive coordinator, the team confirmed Saturday.

Olson spent the past season as the assistant head coach/quarterbacks coach for the Jacksonville Jaguars. He replaces Greg Knapp in Oakland and will work under coach Dennis Allen.

Olson has six years' experience as an offensive coordinator in the NFL, including three with the Tampa Bay Buccaneers, from 2009-11. During that time, Olson was credited with the rapid development of quarterback Josh Freeman into one of the league's more promising players.

Olson favors a power-blocking scheme, which means the zone-blocking scheme favored by Knapp and fired offensive-line coach Frank Pollack are gone after one season.

That should help jump-start running back Darren McFadden, who averaged only 3.3 yards per carry in 2012 and never looked comfortable in the scheme.

Rams running back Steven Jackson had his best season in 2006 with Olson as his offensive coordinator.

Olson also worked with Drew Brees when both were at Purdue and Olson was the quarterbacks coach.

  • The Raiders also hired longtime NFL coach Bobby April to fill their vacancy at special teams coordinator.

    April spent the past three seasons as the Philadelphia Eagles' special teams coordinator. Overall, he has coached 21 years in the NFL, mostly special teams.

    April replaces Steve Hoffman. Allen still needs to add an offensive line and linebackers coach.

    Colts: Indianapolis confirmed the hiring of former Stanford assistant Pep Hamilton as its offensive coordinator.

    Bills: Pat Morris was hired as offensive line coach. Morris has 15 years of NFL experience, including stints with Tampa Bay, Minnesota, Detroit and the 49ers.

    Jaguars: New coach Gus Bradley hired University of Miami offensive coordinator Jedd Fisch to the same position and longtime Chicago Bears assistant Bob Babich as defensive coordinator.
