Baltimore has long been known for their great defense. In 2000, the Ravens had one of the best defenses in NFL history. Some major Ravens defenders include middle linebacker Ray Lewis, outside linebacker/defensive end Terrell Suggs, defensive tackle Haloti Ngata, cornerback Chris McAlister, outside linebacker Peter Boulware, cornerback Lardarius Webb, defensive tackle Tony Siragusa, and defensive back Rod Woodson. Several Ravens defensive coodinators (Marvin Lewis, Mike Nolan, Rex Ryan, and Chuck Pagano) have gone to be NFL head coaches.
