You fail to look at what the overall roster of each of these teams was. The Bears had a solid D and just needed one cog, The O had a good running game and OL. The bills however had a young OL and mostly unskilled Defense. Adding Peppers may have helped generate some rush but teams killed us on the ground and had been doing so for a few years. What FAs could we have signed to fix the D????? I agree that it would have been nice to add experience at both coordinators and still concerned that the current DC is over his head.
