That's quite a statement when you consider the rugged defenses of the Ravens and Steelers, but the Bengals now boast not only the AFC North's top defense but the top-ranked unit in the league. And they aren't showing signs of slowing down. Let's take a look at how the Bengals have become an elite defense in 2011: The fiery defensive coordinator has long been regarded as one of the top defensive minds, and he continues to validate his reputation with his work in Cincy. Through his persistent preaching of toughness and accountability, he has molded the defense into a cohesive unit that adheres to a fundamentally sound approach. In watching the Bengals on tape, their solid tackling and relentless pursuit to the ball stand out. It is not uncommon to see two or three defenders put hats on ball carriers, and the commitment to gang tackling yields minimal yardage after contact. Zimmer has also maximized the talent on the Bengals' defense by carefully assigning roles to his players. His experience directing 3-4 and 4-3 schemes gives him a unique perspective on how to put players in the best position to make plays. For instance, Zimmer has used a variety of players along the defensive line to best match up with the opposition. This has meant more snaps for Robert Geathers and Domata Peko against run-heavy teams, while more accomplished rushers like Carlos Dunlap, Michael Johnson and Jonathan Fanene log more snaps against passing teams. Zimmer's willingness to tweak his game plan and rotations on a weekly basis has enabled the Bengals to throttle their opponents regardless of style.
