In an interview with ESPN 1000, linebacker Lance Briggs predicted the Chicago Bears' defense will be characterized by "aggression" and that it will be a "pretty violent bunch." Briggs quoted new defensive coordinator Rod Marinelli, whose message to the team has been: "Hey, this isn't a 3-4 defense. We're not going to beat people [by] trying to disguise the things we do. We line up with our best 11 and basically kick their butts."
Do the Bears have the personnel to do that? I'll let you decide for now.
The Briggs interview starts at about the 20-minute mark.
