Four weeks after being stymied in their effort to move to Los Angeles, the Raiders agreed to a one-year extension lease extension on Thursday to remain at the Oakland Coliseum through the 2016 season - and possibly beyond. Raiders owner Mark Davis, who had been mulling multiple options to move his team since being passed over by the NFL's other owners to relocate the Raiders to Southern California, called the deal a ''win-win'' for both sides. The deal still needs approval of the Oakland City Council and Alameda County Board of Supervisors.
