Harbaugh using Alex Smith very well. Keeping Smith in his comfort zone. Smith seems to be gaining confidence. Very smart game plan. Niners defense is dominant. Crushing left side of Seahawks’ inexperienced offensive line. Tarvaris Jackson has no time to pass — and when he has time he’s not all that great. Niners seem vastly superior to Seattle. The one issue for San Francisco — it’s hard to judge how good they are based on playing these guys from Seattle.
