Who was the better NFC West team overall in the last ten years?
In the modern NFL that's a long time to be taking stats. Maybe you could do that in the '80s or '90s when the league had dynasties and rosters went largely unchanged. But now, 2-3 years is enough to change the face of a franchise. Look at the Giants for instance now from 3 years ago.
Round up the statistics from 2011 until now and I'm pretty sure the 49ers have one of the best road records in the league, if not the best. As far as competitive play, I saw near Niner wins against the Colts and Vikings in '09 and Falcons in '10.
This team has had a tradition of being good on the road. We won 18 straight road games from the middle of 1988 and didn't lose until the 1991 opener. Beating the 49ers was/is a matter of being better/executing better than them, not where the game was/is played.
And without a doubt since Harbaugh took over, the 49ers have had as good or better road wins than Seattle:
2011 - 49ers 6-2, Seahawks ??? ( but 7-9 overall for season, so probably 3-5 or something)
2012 - 49ers 5-3, Seahawks 3-5 (49ers 1-0, Seahawks 1-1 playoffs)
2013 - 49ers 6-2, Seahawks 6-2 (49ers 2-1, Seahawks 0-0 playoffs)
I didn't have to look up the Seahawks game splits the last two years because I remember they went 15-1 over that span, so easy math. Every other team in the league you'd have to look it up.
Maybe you guys win the 2010 away splits.
You guys did a little better for 10 AM starts last year than we did.
SF has had better road division splits the last few years, and the more recent road victory in this rivalry.
This year might be different but in the Harbaugh/Carroll era so far, SF has been a better road team for sure.
Pull up the DVOA for home/road the last few years, and see how these teams compare.
