Arizona's Levi Brown and St. Louis' Rodger Saffold are tied for the NFL lead with 8.5 sacks allowed. As Cooper notes, offensive linemen aren't always responsible for sacks. Quarterbacks are often more responsible for them, in my view. But Cooper said the stats take care to focus only on plays when a blocker fared poorly in pass protection. He also said physical limitations appear more to blame for Browns' troubles than for Saffold's troubles.
These numbers line up with perceptions. NFC West teams have used quite a few early draft choices for tackles, with mixed results.
San Francisco 49ers right tackle Anthony Davis has become more consistent. He faces a tough matchup against the New York Giants' Justin Tuck. Staley faces Osi Umenyiora. Okung faces the Baltimore Ravens' Terrell Suggs.
