(Renton, WA)  --  There's a good chance Seahawks offensive line coach Tom Cable will return to Seattle next season should the 49ers hire Kyle Shanahan as their next head coach.  ESPN reports San Francisco plans to offer the job to Shanahan, who's currently Atlanta's offensive coordinator, after the Falcons' season ends.  Cable interviewed for the 49ers job on Sunday.  Scott Fitterer, who's the Seahawks' co-director of player personnel, is reportedly a candidate to be the 49ers' next general manager.
