The question of whether a current head coach will be fired comes with a far more important question. Who will replace him? Earlier this week, former Raiders quarterback and NFL MVP Rich Gannon made a suggestion that will capture the imagination of plenty of Raiders fans: Former Raiders coach Jon Gruden. “I’ve had conversations with Jon in the past,” Gannon told 95.7 The Game in San Francisco on Tuesday. “I don’t think it’s outside the realm of possibilities.” Gannon was reluctant to go too far with the Gruden-to-Oakland talk, in large part because Gannon said he thinks current coach Dennis Allen should get a chance to finish what he started. Still, Gannon acknowledged that Gruden will indeed return to the NFL — eventually.
