There are 2 main cover guys for the Bears, Charles Tillman and Nathan Vasher.

Vasher was a 2006 ProBowl selection. Don't throw to his side at all. Tillman has stepped up his game, makes lots of tackles, and won't let anyone past him.

Short passes are effective, especially in the soft spots of the cover 2 (near the sidelines). The Colts have to get their TE some catches to free up the corners of the turf. Peyton can pick apart the Bears that way.

Throw to the center of the field and expect to have your receiver killed. With Urlacher and Briggs patrolling the middle, you're going to get annihilated.
