Al Davis has interviewed prospective head coaches for more than two weeks, two league sources told The Chronicle. But Davis has not yet decided if he will fire Tom Cable. Two people on his interview list have been identified as former Giants coach Jim Fassel, who now coaches UFL champion Las Vegas, and former Raiders offensive coordinator Marc Trestman, the head coach of CFL champion Montreal. Several sources, including one within the organization, believe Davis may re-interview 2009 candidates Kevin Gilbride, the Giants' offensive coordinator, and Winston Moss, a Packers assistant head coach, if he hasn't already.
