"After the Ravens' eighth contest of the season – a 23-20 win against the Pittsburgh Steelers – Joe Flacco was tied for eighth in the NFL in sacks, getting taken down 19 times.

Since then, the quarterback has dropped into a tie for 16th, getting sacked just two times in his last three games. In the Ravens' 16-6 victory over the San Francisco 49ers on Thanksgiving night, Flacco finished the contest without getting sacked for the first time since Sept. 26, 2010 against the Cleveland Browns.

Much of the credit should go to the offensive line, which has appeared to solidify with the return of left guard Ben Grubbs (strained ligaments in toe on right foot) for the game against the Steelers. While offensive coordinator Cam Cameron didn't disagree with that theory, he also offered another explanation."
