'Throughout the preseason, the Bills emphasized run defense, and to great effectiveness. For what it’s worth, the Bills defense apparently didn’t lose a step entering the regular season. While it’s only the Jets, Buffalo held New York to just 38 yards on 15 carries. New York’s 2.5 yards per carry average, again admittedly a small sample size, would easily have paced the NFL last season. The Bills tied for second-best in terms of yards allowed per carry in the preseason.'
