1. Ravens can't run against Cincinnati. Ray Rice is hitting his stride, gaining 153 and 92 yards in back-to-back games. But the Bengals haven't allowed a running back to gain over 66 yards rushing the last three games.
2. Carson Palmer has success in the red zone. The Ravens rank seventh in the NFL in red zone defense. But Palmer has thrown 18 touchdowns and two interceptions when inside the opponents' 20-yard line.
3. Ravens overlook Bengals. It would be easy for the Ravens to lose focus against a 4-11 team that's playing without its top two wide receivers ( Terrell Owens and Chad Ochocinco). The Ravens have had close calls with inferior teams this season.
