Agreed to a certain extent. It just seems that every time the Bears are getting bent over the table it's because they're sitting in a cover-2 zone, or some variation, and the QB for the other team just steps up into the pocket and finds his guy in a zone hole.
The problem is, the Bears rely on a four-man rush more than any team in the NFL (saw a stat on it a week or two back), and it just doesn't work. There needs to be a better design of blitzing or utilizing the front four if the coaches MUST use only them. It just doesn't seem that any DC or HC who has roots in the cover-2 system knows how to design or implement effective rush/blitz packages.
