Prediction time: Ravens at Bears

CHICAGO -- The Baltimore Ravens are looking to build momentum Sunday, which has been elusive for the defending Super Bowl champions this season.

The Ravens haven't won back-to-back games since they beat the Cleveland Browns and Houston Texans in September. The quarterbacks they beat (Brandon Weeden and Matt Schaub) are no longer starters.

Putting together a late-season run has been a trend under coach John Harbaugh. Since 2008, the Ravens have the NFL's second-best record in games Week 10 or later, going 28-13 (.683). Only the New England Patriots (33-7) have a better mark.

Here are the official ESPN predictions (with their prediction record for the Ravens in parentheses):

Jamison Hensley (6-3), Ravens team reporter: Bears, 23-17. The Ravens couldn't beat Jason Campbell in Cleveland, so there's no reason to be confident they can win against a backup in Chicago. Their struggles on the road could end up being the Ravens' downfall this season.
