The Raiders interviewed Mike Martz for their offensive-coordinator vacancy in an attempt to find an upgrade over the fired Greg Knapp, a person familiar with the situation said.

They also spoke with Juan Castillo about the prospect of taking over for fired offensive-line coach Frank Pollack.

The Raiders have not released any information about their search for replacements for Knapp, Pollack, special-teams coordinator Steve Hoffman and linebackers coach Johnny Holland.

All four were fired the day after the Raiders completed a 4-12 season, their 10th straight season without a winning record.

Martz last worked in the league as the Chicago Bears offensive coordinator in 2011. He was fired after a two-year stint. He was the 49ers offensive coordinator in 2008 and worked in the same capacity for the Detroit Lions in 2006-07.

Raiders coach Dennis Allen said in his year-end news conference that he isn't in a hurry to find an offensive coordinator.

"I don't have a time frame for getting somebody in," Allen said. "I want to make sure we get the right guy, and however long that takes for us to get the right guy, that's how long that that takes."

Allen also said he isn't averse to working with an offensive coordinator who has experience as a head coach. Martz coached the St. Louis Rams from 2000-05, earning a reputation as someone who can get the most out of his offense.

"I'll be comfortable with a guy I feel like gives us the best chance to be successful in all areas," Allen said.

Pollack and Knapp came under fire for their implementation of the zone-blocking scheme upon their arrival last offseason. The Raiders subsequently struggled establishing a consistent running attack and scoring points.

Castillo was the Eagles offensive-line coach for 13 seasons before then-coach Andy Reid promoted him to defensive coordinator before the 2011 season. The move backfired and resulted in the Eagles firing Castillo in October of this season.
