On the Seahawks/49ers being villains. I don't know. I mean maybe it's because I am from the west coast so I don't feel it as much. I think there's a lot of respectable people on the two teams, I don't much mind either QB or running back. I think both Gore and Lynch are pretty respectable.
I think partly the 49ers deserve everything more and have a bigger chip on their shoulder. A lot of people on that team spent a long time in a dysfunctional team and they're finally playing good...but also a lot of the younger people are a bit big headed about it. I see the same thing with the Seahawks, but moreso (and I hate Golden Tate, he seems like the biggest asshole ever...maybe I'm still holding a grudge from that GB game though).
Although, honestly, I don't much care for 49ers. Their fans are mostly annoying (I was just in San Francisco yesterday too, blah. Not as bad as when the Giants were in the World Series though) and when they switched out Smith for Kaep mid season I lost a lot of respect for them, especially since I don't think Kaep is that good or better than Smith.
Anywho. I think the Broncos have a better chance if they have to play the Seahawks. I think San Francisco is better overall and are far more clutch when they need to be. The Seahawks' offense has been pretty weak the past few weeks...and I never really liked it much to begin with, and they're bad at playing from behind, which the Broncos could easily do to them.
