Defense needs to make plays come Sunday. Offensively it will be a challenge, and putting points up in Seattle isn't the easiest thing to do. My point being that points are precious in these types of games - last thing you want to do is work hard to put up 7, only to give an easy TD to follow.
Keys To Success
Get Lacy going early - keep the offense dynamic. Only way to beat a defense like theirs is to keep them guessing. Throw a few short passes to Lacy if they have to - but make sure that all available weapons are being used.
Offensive line - Rodgers needs time to throw. This also plays into why Lacy needs to be involved. Bring extra people in to protect if necessary. When dealing with Seattle's secondary - it can take longer for plays to develop, so give Rodgers time to deliver.
Defense needs to get off the field - Lynch is their weapon of choice, and he can wear a defense down quickly. Last thing you want in a potentially close game is a tired D. Playing the run and forcing them to throw would put our defense in the best position.
Rodgers playing 4 quarters - an offensive lull could be enough to give Seattle the driver's seat. Stay aggressive and don't let off the gas.
Don't shy away from Sherman - it is unsure why there weren't any passes thrown to Richard's side of the field in week 1. Regardless of why, it is necessary to use the whole field to spread out their D and keep them honest. Sherman makes mistakes just like anyone else - make him pay for it when he does.
