The Oakland Raiders fired coach Norv Turner on Tuesday following consecutive losing seasons in which the team managed only one victory in its division. The 53-year-old Turner, who had a year remaining on his contract worth about $1.75 million, had known his job was in jeopardy for the last two months after struggling to get the most out of star receiver Randy Moss and an offense that also included quarterback Kerry Collins, receiver Jerry Porter and running back LaMont Jordan. Oakland lost its final six games and eight of nine to finish 4-12 and with one fewer victory than Turner produced in his first season a year ago. The Raiders have strung together three straight losing seasons for the first time since Al Davis came aboard in 1963 to coach and eventually own the team.
