I think anyone semi-competent has the potential to light this Bears defense up. It just is what it is: In the modern NFL, if you can't generate pass-rush, any non-complete disaster at QB will complete passes and score points. Running QBs are even more dangerous and frustrating. I hope that JJ is a disaster QB and has a horrible day, but I'm expecting he frustrates us and puts some points up.
Bears have something coming together offensively though. It's still very strange to think about them as a top 10 offense, given how janky and hurky jurky things have been at times, but they, at least statistically in many areas, are. If Caleb can keep building on some good outings, if they can keep that running game going (and I think commit just a little bit more to it) and receivers can keep passes in their hands, they win this. But, a lot of ways for this to go wrong, of course. It's still a work in progress, but the progress is proceeding nicely.
