This week's Game of the Week is a rare, quality Monday Night matchup. The Pittsburgh Steelers travel to the west coast to take on the San Francisco 49ers, who are suddenly falling back to earth after a Week 14 loss to Arizona. Kerry Byrne examines a quality statistic that shows a real flaw with the 49ers that Baltimore was able to expose on Thanksgiving night, and thinks that the 49ers might struggle again to protect their quarterback against a stellar defense.
