The scriptwriters for the 2016 Bears season sure had a warped sense of humor. Before everything went so far off the rails, they penned such a perfect start. Those who haven't locked the memories away in a deep, dark place will recall the very first drive. The defense against Brock Osweiler and the Texans. Second-and-8 from the Bears' 34-yard line. Veteran cornerback Tracy Porter matched up with Pro Bowl receiver DeAndre Hopkins in man-to-man. As Hopkins ran a 13-yard out to the left sideline, Porter stayed velcroed to his outside hip. When the ball arrived, Porter ripped it from Hopkins' hands. Interception. In that moment, it seemed the Bears' defense might return to its ball-hawking ways of the Lovie Smith era. But it was a mirage most cruel. The Bears forced only 10 more turnovers the rest of the year, finishing tied for the lowest single-season total in NFL history. "We need to add more ball skills to our secondary," general manager Ryan Pace said after the season. "That's on me, and we'll do that." Well, the time has come. The NFL draft begins Thursday, and this year's class of cornerbacks and safeties is widely regarded as deeper than any in recent memory. The Bears, then, have a glorious opportunity to upgrade.
