Honestly, I'm not at all invested in facing SF again. I don't care who we play as long as the defense brings it, the offense gets working, and the team limits stupid penalties. If they do that, there's not a team in the league that beats them, especially in Seattle.
With that said, the teams that have given Seattle a tough go this year aren't the teams with explosive offenses, but those with stifling defenses. Both Rams games saw our offense struggle. The road game against SF, last week's debacle against Arizona... our division is brutal when it comes to defense.
So I guess if I'm looking for the Seahawks to have the best shot to make it to the SB, then I want them facing the Saints, Eagles, or Packers - teams with questionable to downright bad defenses. I have confidence in our defense shutting down ANY opponent's offense, but I don't have full confidence in our offense producing against tough defensive fronts like SF or Carolina.
