I think it is important to remember the Bears aren't being forced to build an elite defense. They need to have a reasonably effective defense, because their offense is awesome and will win games. They haven't acquired, and weren't exactly looking for, individual difference makers. They have acquired several guys who are reasonable upgrades to what was there before, who, for the most part, can make the occasional impact. Allen isn't going to play every snap. And since he's not making $12m you don't have to justify the cap hit with unnecessary playing time. If they can just field a defense that flirts with average, they will win a lot of games next year. And they are well on their way to doing that. The biggest question to me remains the coordinator.
