New Raiders general manager Reggie McKenzie is contemplating whether to keep Hue Jackson as coach, according to league sources. Agent Kennard McGuire, who represents both men, has denied that Jackson would be let go. McKenzie, a former Raiders player and Packers executive, will be introduced Tuesday as Oakland's general manager. He will become the first Raiders executive to hold the title of general manager, and sources claim he is contemplating whether he should bring in his own coach, despite the relationship with Jackson.
