(1) How will rookie quarterback Mitchell Trubisky and the Bears offense respond after struggling in last Sunday's loss to the Eagles?
The rookie first-round draft pick posted a season-low 38.3 passer rating while quarterbacking an offense that failed to pick up a first down in the first half and never advanced into the red zone in a 31-3 blowout loss to the NFL's best team. Trubisky and the rest of the offense will look to rebound Sunday against a 49ers squad that has the NFL's second-worst record at 1-10.
