I dont watch the Seahawks closely, but I've seen multiple games, in fact most of the games I've watched of them the last two seasons, where they will run clock with strictly their running game. They will have a lead, and go extra conservative, but get 1st down after 1st down running the ball three straight times. It will be an obvious running play, but not matter. They still get positive yards. They are vastly underrated running team.
There is no doubt that everything works well together...strong run gane, mobile qb, and AVERAGE throwing talent
