Moore has nothing to do with Philly's OL. That's all Stoutland. He's the best OL coach in the league and has been for a few yrs. He's not going anywhere
Sorry to say but I'll bet Kubiak takes a Benton and Dennison with him to Sea.
Moore may not be the one coaching the OL, but his offense and the success of his offense is a direct result of that OL. He might not be able to bring the OL coach, but he's damn sure gonna try to build something similar here.
