In Week 12, Chargers quarterback Philip Rivers set an NFL record by completing 25 passes in a row against the Cardinals.

In Week 13, the pass defense did a 180-degree turnaround, forcing Packers quarterback Aaron Rodgers into one of the worst games of his career. The conditions were certainly suboptimal on Sunday and Green Bay drops helped the cause, but the coverage against the Packers was markedly improved.

Rodgers finished the game 31-of-50 passing for 233 yards with a touchdown and no interceptions. Rodgers' yards per attempt figure of 4.66 was the fifth-lowest of his career and his worst mark ever at Lambeau Field.

Coach Steve Wilks said the players did a great job of not tipping their hand before each snap.

"I thought it started with our disguise," Wilks said. "I thought we did a great job of trying to show them different looks, trying to hold what I consider the (Cover Two) shell and not really trying to show our rotation too soon. It got them a couple of times. I thought these guys were prepared. I thought the coaches did an outstanding job in showing them the different looks throughout the week, and it was the same thing we saw yesterday in the game."

One of the key factors was limiting the big play. In today's NFL, quarterbacks are going to complete passes, but none of Rodgers' went for more than 19 yards.

The Cardinals' secondary won't have time to bask in Sunday's success. The final four games feature matchups against quarterbacks Matthew Stafford, Matt Ryan, Jared Goff and Russell Wilson.
