Ravens: What are the Chances...?

The Steelers are a three-point underdog tonight on the road vs. the Ravens. While it figures to be a close game (the past 7 meetings have been decided by a total of 31 points, including 2 OT games), I'd estimate that Pittsburgh has just a 45 percent chance of winning. Though the broken bone in Ben Roethlisberger's foot could hinder his effectiveness, it's the Steelers' banged-up offensive line that is most likely to compromise Pittsburgh's chances.

What are the Chances...? is 7-4 thus far in 2010, and 55-24 all-time.
