I don't have any feelings for them one way or the other. They're a division rival so I gotta hope they lose if it affects the Rams in any way. I might have a little disdain for the seahawks, being that they're defending champs and have owned us most the time lately.
Now the 49ers are a different story. I will always root for them to lose. I watch a lot of 49er games because every week aside from Rams week they play my second favorite team, whoever plays the 49ers.
