With Atlanta having the home field through the playoffs wrapped up, why do you care? Are you rooting for Seattle because you think San Fran is better and want them on the road in the playoffs? If so, you might not want to bother. They are perhaps the best road team in the NFL.
I'm a Falcons fan, and Seattle is the LAST team I want to see in the playoffs. They are on fire right now. They have the look of the past few SB winners- lay low all season, get hot in December, and ride it all the way to a championship.
