Joe Flacco was pressured on 18 of his 42 drop-backs Sunday, and was sacked five times as the offensive line once again struggled to protect the quarterback. Through 10 weeks, 22 offensive lines have allowed fewer total pressures than the Ravens, who have allowed 126, according to Pro Football Focus. The Arizona Cardinals, with 143, have allowed the most. Also, Flacco has been sacked 30 times. Only two quarterbacks have been sacked more often, though the blame for that does not fall solely on the offensive line. Pass protection issues for the running backs, the inability of receivers to get open and the indecisiveness of Flacco himself are also factors.
