If you use the term "Monsters of the Midway" it is almost guaranteed that your listener's mind will flash to picture of a linebacker. The history of Chicago defenses was written in large part by legends who occupied the linebacking corps. Bill George, Dick Butkus and Mike Singletary are all in the Hall of Fame and Brian Urlacher will join them soon enough. As a result, thinking about linebackers as the driving forces of defense in the Windy City is a natural reflex. But times have changed and the current Bears linebacker's depth chart is nothing but a remodeling job that is about one third of the way completed.
