If the Cardinals play up to their abilities and execute the game plan then they will win. Yes Green Bay will be somewhat healthier coming in but they just can't match up with the Cardinal receivers and the Cardinals need to be able to run just enough to force Green Bay to respect the run game. 3-5 yd. chunks will provide enough to force Green Bay to play honest on defense. Unless Green Bay goes into max protection mode for Rodgers their Oline will not stand up to the Cardinal defense. If they go max protect then Rodgers will find no one to throw to and the defense will get coverage sacks.
Even Brian Billick doesn't buy what the media is selling that Green Bay is back. What is making a lot of people nervous is the babble the media is spitting out that Rodgers is back and Green Bay has righted the ship. All they have really done is patch a few holes in the boat. The Green Bay ship is not ready to navigate the Red Sea.
Rodgers was 21/36 for 210 yds. and 2 TDs. Not exactly what you would call a breakout game like the media is calling it. You can name 30+ other QBs who had numbers like that in 2015. Cousins threw for 329 yds. and 1 TD against the Green bay defense. Last time I checked Kurt Cousins was no Carson Palmer.
Washington was 25th in pass defense and 25th in run defense, not exactly what you would call a tough test for an offense. The Cardinals on the other hand are 6th against the run and 8th against the pass. Washington best win was over an 8-8 Bills team and they lost to the Dolphins, Jaguars, Cowboys, Falcons and Giants. Washington was way overhyped coming into the game with GB. The Cardinals beat 3 playoff teams, GB, Seattle, and Minnesota.
The only team that is going to beat the Cardinals this Saturday is the Cardinals. Yes, GB will score more points than the first game and it will be a closer game for a longer period of time however in the end there is no reason why the Cardinals should not come out on top. I fully expect the Cardinals to win with a 10+ point margin and if the Cardinal defense can make GB one dimensional on offense early, then it may very well be another blowout like the first game.
