Raiders bring back Greg Knapp as OC

Oakland Raiders coach Dennis Allen has made the first hire for his staff, bringing back Greg Knapp as the team's offensive coordinator. The Raiders announced Knapp's hiring Wednesday. Knapp spent the past two seasons as quarterbacks coach in Houston but was coordinator in Oakland for two years under Lane Kiffin and Tom Cable. Knapp has 17 years of experience as an NFL assistant, including stints as a coordinator in San Francisco, Atlanta, Oakland and Seattle. He helped the Texans make the playoff for the first time in franchise history in 2011 despite losing starting quarterback Matt Schaub to a season-ending foot injury after 10 games. Backup Matt Leinart also got hurt and Knapp groomed rookie T.J. Yates, who helped the Texans beat Cincinnati in the first round of the playoffs.
