Counting Cards: Part III of III

The last time the Packers faced the Cardinals, AZ walked off with a 38-8 win. It was only the ninth time a Rodgers led team lost by 15 or more points. The Packers are 32-9 when the final score is decided by 15 or more points under Aaron. It was a pummeling. It was a bloodbath. 8 sacks surrendered to the Cards, and two fumble returns for TDs, plus another fumble on the Packers first play of the second half to give AZ and easy touchdown to start the half.
Let's start with the defense.
Sam Shields is a great cover corner. He is sticky, fast, quick, and jump, has ball skills, is a good tackler. He is a Pro-Bowl player. When healthy. In 16 regular season games, Shields played 12. the Packers surrendered 214 points in games that Shields started (17.83/gm),  and 109 in which he missed due to injury (27.25) including the 38 to the Cardinals. Carson Palmer thrives of tons of underneath throws opening up the deep game. Shields can cover both. He can play against big guys (he covers Dez pretty well and has a 39'' vertical) and shifty guys (6.79 3-cone drill and 11'1'' broad jump). He can cut out the deep game (4.3 40 yard dash). He can intercept balls (former college wide out). He routinely shuts down Post, Sideline, Seam, Curl, and Out routes. Only on In routes and big double moves does he have more trouble than not. He is the best corner the Packers have. With him in, I trust the pass defense, and therefore the base defense can be lined up to limit the run game (24 rushes for 123 yards) and the screen game (Johnson had only 3 catches, but for 88 yards [44, 29, and 15 yards]) as well.
On the O line, we didn't have Bakhtiari. In the last two games of the season (no David) Green Bay nation watched their beloved QB go down 13 times, nearly triple their annual rate. If he plays, I see the sacks against AZ (8 in week 16) getting cut in half at least. The rush will also buy more time for completing passes (15/28 for Aaron). I can envision the passing game having half again as much success (60+ completion rate, 7 yards/attempt, etc.). By also using Cobb in the backfield more, it disguises the play (look at the success against the Patriots in 2014). The running game is getting going more (140 yards on 29 carries from Lacy, Starks and Cobb against Washington, 123 yards on 20 carries in the second half alone). And if McCarthy goes with 6 lineman against the Cards, that could make improve things. After all, I trust our sixth lineman more than our 4th receiver against perhaps the fastest defense in the league.
So, limit the fumbles (-21 points, AZ), increased time in the pocket (+10 points, GB) and better running game (+10 points, GB). However, the Cards won't be letting their foot off the pedal this time. I see a potential slugfest.
Or we see a Cards team that is the best in the league dominate a flawed Packers team.
