The pick: Bears (+3.5) over Cowboys
Dallas is going to have trouble on both sides of the ball. Offensively, the line may struggle against Henry Melton, Julius Peppers and co. The Bears have done a good job getting pressure on the quarterback so far this season. They have 14 sacks through 3 games. For the Cowboys, the line has had a difficult time getting in sync -- I honestly don't think it's a talent issue, but rather one of cohesiveness.
Defensively, Barry Church's injury really hurts. He played exceptionally well at safety, and his loss may mix things up in the Dallas secondary -- especially if Brandon Carr moves over to safety as he did at times against Tampa Bay. Without Carr lining up against the Bears' monster WR duo of Alshon Jeffrey and Brandon Marshall, Mike Jenkins will have to remember how to play corner or 5'5" Orlando Scandrick will get eaten up. Plus, you have a rookie on the other side who would likely be stuck with Marshall, one of the league's best.
In short, Romo has to be Romo from the Giants game and the defensive secondary has to play their best game for the Cowboys to win. Unfortunately, that probably won't happen. Look for some improvement on offense and hope for the best if Napolean Scandrick gets a lot of snaps.
