1. The Bears force turnovers. Chicago has the most takeaways in the NFL since 2004 with 195. Cornerback Charles Tillman is tied for the league lead with six forced fumbles this season.
2. Chicago's dangerous returners win field-position battle. The Bears' special teams can influence the game with two of the league's best kickoff returners ( Danieal Manning and Johnny Knox) and big-play punt returner Devin Hester. The Ravens' coverage teams both rank in the top four in the NFL.
