Da Bears have got it going on on defense: tough against the run and dominating with a well-organised zone defense deep. They will pressure Matt Stafford all day without having to send everyone and unless Detroit lean on the promising Mikel Leshoure, it may be a long night under centre.
Matt Cutler won't have an armchair ride either, with his usual porous offensive line struggling to keep him upright. However, with Forte and Bush in the backfield, they have the ability to mix it up enough to let Cutler take some shots.
The crucial difference may be on special teams where Chicago are once again strong. That, and their defense, should give them a touchdown's advantage.
Pick: Chicago Bears -6.5 @ 1.95
