When you're hoping to win a game with your quarterback in inclement weather, as the Packers are, losing an elite run-defense LB is exactly what you don't want. Which is what just happened to the Packers, with Nick Perry out and Clay Matthews playing with one arm. If that allows Thomas Rawls to run rampant, it will let Seattle control the clock and keep Aaron Rodgers off the field, negating any attempt of his to exploit Steven Terrell.
Plus, Green Bay just changed centers. That will help negate any disadvantage our pass rush might have in the snow.
That said...I'm still more respectful of Rodgers than I am of anyone else we've beaten this year. It won't be a blowout.
