Football Outsiders has a stat called adjusted line yards, which is a formula that measures a running back’s carries, and assigns responsibility to the offensive line. The 49ers are comfortably the best in the NFL. On average, the offensive line is creating 5.4 yards per carry for the running backs before they are being touched. Think about that. The next closest team is Buffalo, at 5.09 adjusted line yards. Almost a half-yard difference between first and second place.
