A coaching crossroads in Oakland

Things could get interesting in Oakland.

ESPN’s Adam Schefter is reporting that the San Francisco 49ers have requested permission to interview Oakland offensive coordinator Hue Jackson for their open head-coaching job.

I can tell you this: There is no way Oakland owner Al Davis will want to see his offensive coordinator go to Bay Area rival San Francisco. There is no way Davis could sit and watch Jackson resurrect the 49ers and have the entire Bay Area wonder how Davis let Jackson get away to the 49ers.

Schefter reported that Oakland coach Tom Cable is unlikely to return. Cable has done a nice job getting the Raiders to .500 for the first time in eight years. I have long thought the only way Cable will be fired is if Oakland promotes Jackson, who dramatically improved the Raiders’ offense in one season as offensive coordinator.

If Davis fears the 49ers will hire Jackson away, he could make the switch. I think that could be the case if Jackson gets a chance to be a head coach anywhere. But if a team like the 49ers or Denver made a move for Jackson, it could surely prompt Davis to make a change.
