My only stab at it is maybe instead of a complete overhaul of Hackett's offense they have changed say 50% of it. Maybe during this lengthy TC they were able to work on a bunch of new wrinkles and showed none of it during their preseason games. I have a sneaking suspicion that the offense will be able to move the ball against chicago easily. We may even see a bit of it against detroit tomorrow night. I don't agree with being completely Vanilla during these preseason games but as long as they are getting in the work during camp practices it will be fine....guess we will find out in 10 days
