Both Seattle's defense and offense are only going to improve, and if that's the case, they're the best team in the NFC WEST. They have a better QB than the 9ers, and NO TEAM could come into Seattle and do what the Giants did to the 9ers on Sunday. Don't let the past blur your ability to recognize what's going on out west. This division is really, really good. Likely the best in the NFL top to bottom.
Well now Seattle has to go undefeated within the division the rest of the way if they are going to contend for the division. They are 0-3 against NFC West teams. As far as what the Giants did to the 49ers last week, Cincinnatti did it to Seattle last year 34-12 along with the Falcons 34-18, Chiefs 42-24, and Giants 41-7 the year before. Its still too early this year to say that nobody can go into Seattle and beat them handily,
because Seattle just isn't very good on offense. I do agree with you though, this division is stacked on defense, offense not so much.
