As bad as Cincinnati's offense was last night, the defense was that good. Nick Foles isn't an all-star quarterback, but he was held to under 50 percent completion, and Bryce Brown was limited to only 34 yards.
The defense—Vontaze Burfict namely—was in Foles' face all night and forced five turnovers. Mike Zimmer has quietly been among the league's best defensive coordinators over the past three or four years, and after the bad start this season, he's brought the 2012 version of the Bengals defense near the top.
He's a blessing that will likely leave Cincinnati following the season, but for now, he's keeping his defense performing well.
