So from a Seahawks perspective.
The #1 thing I feared was playing the Saints in the playoffs in that dome. It is impossible to win there. I don't fear the Saints in the clink, but they are a different animal in that dome. So we can scratch that one off the list.
Next up is the Rams, just because Aaron Donald wrecks every game, and they match up well with the Seahawks.
Dallas is third for now, they are healthy and complete. They will drop like a stone if they have injuries on their O-Line though.
49ers because they can score points, and have a beastly D-Line that could give the Seahawks trouble.
As some have pointed out it is way too early to be having this conversation. No point in discussing until week 10ish when things have sorted themselves out a lot more.
I do know the Seahawks are in the mix as contenders. They have an elite player at QB. They can run the ball. Pete will work his magic on the defense. And they are damn good in the kicking game.
