I posted about this early last season, about why I thought the Seahawks would peak late in the season and be the best team in the NFL (whether they won the SB or not - as they were at the end of the season before).
By the mid-to-late season, with all the bumps and bruises a season lays on players, you see more and more "business decisions" made by the opposing players. The same thing will happen this season. I don't know if they will win 12 or 15, or whether they will actually win the SB with so many variables, but I do know that they are the best team already, and they will be even better than they are now (and were last year) by mid-season.
There is no team that does things the way this one does.
