Seahawks have lost fom their 2013 roster, offense and defense:
OT Breno giacomini
DT Clinton Mcdonald
FS chris maragos
WR golden tate
WR sidney rice
DE chris clemmons
DE red bryant
They wont be exactly the same, but they should be top 10-12 defense. Thing is, GOOD defensive coordinators figure things out and know how to combat them. If we have any chance at all in winning in their house, it will be from the added threat of a good ground and pound game helping to open up play action pass. Now seattle will have to lean on their offense a lot more this season to put up pointa as I think their D wont be as productive in helping to put points on the board. Which means russell wilson will actually have to stand in and throw the ball more times and like someone already said, Lynch is not the beast mode he used to be and RB age is creeping on him with a quickness. They will be contenders, but I HIGHLY doubt they will repeat or even go to the SB again this season.
