On Sunday I watched the 49ers and Eagles go completely flat on the road against two opponents, who I would guess, they didn't expect to be a serious threat (Vikings and Cardinals). That's the danger in tonight's game in Seattle, and I hope the Packers are prepared for it. There seems to be little separating a lot of teams in the NFL this season.
It's been a quiet week for the Packers, so while I had some questions about the role and status of WR Greg Jennings and RB James Starks last week, they don't seem to have resolved themselves before the start of the game.
The Packers injury report isn't huge, but it has a lot of uncertainty on it. Backup LB Jamari Lattimore is clearly out, and it doesn't look good for TE Tom Crabtree either. CB Davon House doesn't appear to be fully recovered from his preseason shoulder injury.
I'd be surprised if RG Josh Sitton can't play, but he was limited in practice all week. If he can't go then OL Evan Dietrich-Smith would start in his place. The uncertainty surrounds Jennings, Starks, and DE C.J. Wilson, who all look like game-time decisions to me. But I don't expect it'll be a problem for the coaching staff, who've had all week to prepare for the absence of all three players.
The Seahawks appear to be in good health, with only WR Doug Baldwin apparently out for the game. WR Sidney Rice was curiously listed on the injury report with "Rest" instead of an actual injury. It's common for a team to sit out a veteran who has a long-term injury, but the Packers would list an actual injury (i.e. LT Chad Clifton was usually limited each week in practice due to his chronic leg injuries).
