So last year the Bears defense finished 1st in the league in DVOA by a large margin (not sure the run/pass splits). This year they are much lower especially against the run. Just curious what people think the biggest reason is, considering there are several areas you could point to. -injuries to Briggs, Tillman, Melton, DJ Williams, Paea -losing urlacher and izzy (am I missing some losses?) -new defensive coaching staff -age leading to decline -poor drafting Obviously it's a combo of all and more but which one was the biggest reason the defense is embarrassingly bad? How do we get this fixed?
