How the Bears' defense would look without Brian Urlacher was a big question mark entering the season. The answer: Rely on stud veteran defensive backs who force turnovers.
Tillman had an interception that set up the Bears' first touchdown. Later in the half, the ball found the cornerback again as he snatched a bobbled pass off Green's hands, ending a promising Bengals drive.
Green was the star of the first half with two touchdowns, putting the Bengals up 14-10.
But the Bears' defense kept them in striking range. And strike the offense did.
Coming out of the half, Cutler got Chciago in gear by spreading the ball around in a fairly balanced offense.
However, on the decisive drive, Cutler went back to his security blanket, hitting Marshall three times on the drive for 63 yards and the winning score.
Trestman probably will hope his offense clicks earlier in upcoming weeks, so as not to rely on an opportunistic defense. But in his first NFL game with the head job, Trestman will take the win.
