Norv Turner, fired as coach of the Oakland Raiders two weeks ago, moved across San Francisco Bay to become the 49ers' offensive coordinator on Tuesday. Coach Mike Nolan hired his former boss with the Washington Redskins to replace Mike McCarthy, named the Green Bay Packers' head coach last week after one terrible season with the Niners. Turner, who also coached the Redskins for nearly seven years, was fired by the Raiders after just two losing seasons. But the Bay Area native still is considered one of the NFL's top offensive minds, with a career highlighted by his work as the Dallas Cowboys' offensive coordinator during two Super Bowl-winning seasons.
