Eh! I think the advantage of not having to fly to the West Coast in the middle of the season and then fly back is a bigger advantage than having to face the Seahawks at the start of the season before the team is clicking on all cylinders.
And we don't know if the Pats would come out with a slow start. Last year was different because there new coach, new system, and a lot of new starters including a bunch of rookies. Last year, the entire o-line except for Owenu was new with two rookies manning the left side of the line. This year will be different since it will be year two and at most there will be one or two rookies starting.
