I think the Seahawks have a fairly difficult schedule.
First off, I don't think Arizona (depending on if QB and O-line needs get filled) and St. Louis (healthy next year) are going to be pushovers again. San Fran might need another year as they groom Alex Smith more. It changes if they happen to get Reggie Bush somehow.
But I certainly worry about these teams due to the talent that should be prevalent next year: Oakland, Minnesota, San Diego, NYG, Chicago, Denver, KC, and Tampa Bay.
One extremely fortunate side note is that many of the east coast teams have to come to us, rather than the other way around. We have to make one long trip down the Tampa and another tough one into Chicago, but I don't fear going to Detriot and Kansas City isn't too far away.
The rest of the teams are on the West Coast so there isn't any effect from time difference.
Still, I see some real letdown from this year's easier schedule. Hopefully some of the better teams have similar problems.
