LAKE FOREST, Ill. (November 1, 2012) -- The Chicago Bears had some question marks in their secondary when the season started. It turns out they had some answers, too.

With the defensive line applying the pressure up front and the guys in the backfield letting little get past them, the Bears lead the NFC North at 6-1.

They keep coming up with big plays. They keep getting recognized for it, too, with Pro Bowl cornerback Charles Tillman being selected NFC Defensive Player of the Month for October.

All he did was return two interceptions for touchdowns, limit Detroit's Calvin Johnson to just three catches for 34 yards and help hold opposing quarterbacks to a league-low 61.9 passer rating while the Bears went 4-0. A month earlier, Bears cornerback Tim Jennings won the award.
