Unlike San Francisco, Chicago seems to have put those struggles behind it.
Kyle Orton and the Bears try to extend a four-game winning streak and maintain their lead in the NFC North when they face the 49ers at Soldier Field.
Chicago named Orton the starter after Rex Grossman suffered a broken ankle in the preseason. In a division that features Brett Favre and Daunte Culpepper, the Bears figured to struggle with a recent fourth-round draft pick running the offense.
