Thanks for that site, cite. I've always like Barnwell who is nicely quantitative. I, also, do not understand the "ranking." After 2 preseason games we know very very little and even after a full season most ranking schemes are poor IMO (e.g., Total Yards). I also agree with the sentiment of those that say we won't know until the first real game. I'd make a technical amendment that we actually won't know until the last game. The Bears defense in 2013 looked its usual quality self for the first three games.
