OAKLAND, Calif. � Disgruntled Oakland Raiders fans are making a high-profile plea for owner Al Davis to step down as the team�s general manager.

A billboard was posted on the freeway near the Oakland Coliseum this week, saying �MR. DAVIS, DO THE RIGHT THING, PLEASE HIRE A GM.�
The group the put up the billboard says it has gathered 21,000 signatures for a petition asking Davis to step down as general manager. The petition also calls on Davis to hire a new GM, hire a Super Bowl-caliber coach, and �agree to refrain from intervention in personnel or football operational matters.�
The Raiders (3-8) have won three Super Bowls under Davis� leadership but appear headed to a seventh straight losing season. Oakland�s 27-80 record since the start of the 2003 season is the worst in the NFL.
