Each Wednesday throughout the season we'll identify one player, coach or area of the team that is most under the microscope. This week, it's the Bears' run defense.
Running backs didn't have much success against the Bears in the first half of the season.
They held the Bills to 46 yards rushing in Week Nine, and rank third in the league vs. the run, giving up just 83.9 yards rushing per game. The Vikings' Adrian Peterson is quite capable of making a sturdy run defense implode, however, and he has shredded the Bears in past meetings.
Peterson has scored at least one touchdown in all six games he has played against Chicago, and he has 11 TDs total in those six contests. Prior to last season, when the Bears held him to less than 100 yards rushing both times they faced him, Peterson had snapped off games of 121, 131 and 224 yards rushing in the previous three games against them. He has a 4-2 record all-time against the Bears.
Chicago's front seven will have to put forth one of its better efforts of the season to keep Peterson from busting loose. The Vikings have the weapons to move the ball through the air if they have to, but forcing Brett Favre to throw because Peterson can't get free is the scenario the Bears would prefer.
