Lance Briggs plucked the ball out of the air and started rumbling down the field. As the Chicago linebacker approached the end zone, he fully extended his right arm over his head with the ball in his hand. Briggs and the rest of those 30-something Bears defenders showed Tony Romo and the Dallas Cowboys how much they can still play. Charles Tillman, another of the five defensive starters in their 30s, also returned an interception for a touchdown in the Bears' 34-18 victory Monday night.
