I'm a 49ers fan...but I'm also a realistic fan.
SF is VERY lucky to be 2-0. Yes, they are wins, but if they play any decent team they will get curb-stomped if they keep playing the way they are. The offense is not good outside of Gore. If a team stops the run and constantly pressures Smith, they aren't going to score.
They will need to get Vernon Davis involved in the game if they want to move the ball with regularity. He has 27 yards in two games. TE's are the safety valves for many teams (SD, BAL, NYG)...I honestly think that if Davis gets the ball more often, it will make the defenses think about stopping the pass along with the run.
Anyway, I'm going to be at the SF-PIT game on Sunday. I fully expect the 49ers to lose. Something like 27-6 sounds about right, but I'd sure love to be wrong.

Oh, right...the actual question. It'll be Seattle or SF. I'm still not sold on my Niners, so I will need to see them beat the Seahawks before I can believe it's their year.
