Two days before his preseason debut as an NFL head coach, Matt Eberflus talked about the two perspectives he must maintain as he begins his quest to turn around the Chicago Bears. The telescope view, he said, is about where the Bears are headed long term. Saturday’s preseason game against the Kansas City Chiefs is about the microscope view as Eberflus, his staff and his units work out the kinks of operating together in a game setting for the first time. “I’m just focusing on having good game-day operation, working on the scheme, evaluating the personnel for this first game,” Eberflus said.
