Seattle wins because of defense and their running game. Last year, Seattle was in a slump and they started to get their mojo back once they started giving the ball to Marshawn Lynch once again. They don't win by good defense alone and it also the run game helps set up Wilson with a lot of play action.
As for us going to the playoffs last year, it was because of our running game. The run game sets up the pass. We ran mostly on 1st and 2nd downs which we gave us a lot of 3rd and short situations. Having Murray in on 3rd downs during those situations made it hard for defenses to play against because they didn't know whether if we were going to run or pass. Why do you think that Romo had his best year ever? He also had the one of the highest if not the highest conversion ratings on 3rd downs.
The run game also kept our defense fresh because we were able to control the clock. Last year we had the worst defense in the league and we also lost Ware and Hatcher. Thus one of the main reasons why we improved on defense was because we ran the ball and kept them fresh throughout the game.
We got to the playoffs because of our running game. Once we started running the ball everything on our team improved including the passing game.
sigh...
Please do not post things without fact checking them.
Some of you guys have agendas and very poor memories.
SEA lost 5 games all year, only once had a losing streak of 2 or more games.
They came out of that streak by running Lynch all of 14 times; 4 less then the loss the week before.
There last two losses of the year were with Lynch running 24 times each.
SEA was carried by the best secondary in football and a strong running game.
That running game was based upon Lynch being assisted by 850 yards rushing from the QB.
Lynch averaged 18 carries per game in wins and 16.4 in losses. The difference is almost solely due to the 6 carry game in the week 2 loss to San Diego.
SEA got better when it got it's LB corps back and started stopping the run again.
