Hue Jackson is moving into a more familiar role with the Bengals. The team announced Wednesday the promotion of Jackson to running backs coach with the added title of special assistant to head coach Marvin Lewis. “Hue brings a wealth of experience,” Lewis said. “He’s been an offensive play-caller, an offensive coordinator, been the head coach. So he has the perspective that (offensive coordinator) Jay Gruden also has, and that’s helpful. “Hue being back here this year, he looked at things so much differently having been a head coach for a season. He’s a great resource that way.” Jackson coached the Raiders to an 8-8 record in 2011 but was fired after that season. The Bengals re-hired him last year as an assistant defensive backs and special teams coach. Adam Zimmer was hired Tuesday as the new assistant defensive backs coach. Jackson, 47, takes over coaching the running backs for Jim Anderson, who retired last week after 29 seasons with the team. “I have to do everything I can to keep that same standard, keep it as high as it’s been,” Jackson said. “He did a tremendous job here. Following him, there’s some pressure to that but I’m looking forward to the challenge.” The Bengals ranked 18th in the NFL in rushing offense this past season and were led by running back BenJarvus Green-Ellis, who finished with a career-high 1,094 yards. The Raiders ranked No.2 in the NFL in rushing with Jackson as their offensive coordinator in 2010 and were No.7 during his season as head coach.
