I find the pessimism quite astonishing really, but I think most of it is driven by relativity to 2013 (i.e. 'its obvious we are not what we were' line of thinking)
When we were healthy, we tonked Green Bay, beat Denver (should have been comfortably), should have thrashed the Redskins and lost a game in San Diego due to the defense not getting off the field (not entirely excusable but the TOP killed them in the heat). Conditions for rest of year as temps drop = Seahawks football weather more than anything else.
I was hugely relieved with the Carolina win, given the injury situation I feared for that game. The season is still intact and with getting so many starters back I would prefer to back the Seahawks than their opponents in any matchup left in the season.
Once Wagner comes back, the defense is going to be strong, hopefully the injuries slow down because the secondary will be fierce and importantly DEEP, the linebackingcorp has various package options with KPL,Smith, Wags, KJ to hopefully allow Irvin to play at DE to help the D line cope with less depth.
On offense, once the O line gets back to Okung Carp Unger Sweezy Britt I think Wilson will have a bit more time and his composure will step up markedly. Think Norwood and Richardson can make a big impact if Wilson gets an extra second to throw. O Line is a good run blocking unit from what I've seen (JR and Carp impressed me), and no they will not be a good (or even average) pass blocking unit but they can get the job done, they don't have to be lights out.
I look round the NFC at the moment and I don't fear anyone. Eagles / Cowboys will have to manage injuries to QB, 49ers look likely to miss, NO can't play away from the Dome, Green Bay we stomped, Cardinals? Well i'm not sold on Arizona yet, lets wait and see what they do in regular season play against us. Lions? I saw last week in London and Stafford without those weapons look awful, can't see them holding Green Bay in the North.
So call me optimistic, unrealistic (?) but I see us going 11-5 or even 12-4 IF our injuries don't continue at this rate. Get through the play-offs finding a way, to leave us with a confrontation with Brady, Peyton or 'superstar' Luck for all the marbles.
