The Bears' top priority during the offseason was to revive their defensive line. They signed five free-agent defensive ends, re-signed a veteran three technique and drafted two defensive tackles, all with the hope of restoring its fierce, disruptive presence.

So the most important takeaway, good or bad, from Friday night's penalty-marred 34-28 exhibition victory at Soldier Field was easy to find looking into the Eagles' backfield.

The Bears pressured starting quarterback Nick Foles into two interceptions. Yes, it was only an exhibition, so all of the necessary qualifiers apply. But seeing the Bears' defensive line win in the trenches against the Eagles' first string was the most significant evidence to date that the line has regained a pulse.

“Our defensive line is going to be real,” said second-string end Trevor Scott, who helped pressure Foles into his second interception. “That’s one of the big things we want to focus on this year.”

Overall, the Bears advanced from their first exhibition with a few positives on which to build and more than enough coaching points to last until Thursday's exhibition against the Jaguars.

In a game for which the Bears did not scheme for the Eagles on either side of the ball, the defense forced four turnovers, and Jay Cutler quarterbacked the first-string offense on a 13-play touchdown drive.

But they surrendered a 102-yard kickoff return for a touchdown, turned the ball over three times and were assessed 14 penalties for 103 yards.
