Not sure that I see the D Line playing better than the O-Line. Actually, I am sure, no chance. The D Line generated very little pressure, only on a few plays, mostly Goff stood back there and threw, luckily he can't hit open receivers or the Eagles would have lost.
The OLine did at least control the defense enough for over 200 yards rushing, much of it Hurts running for his life.
The DLine also did almost nothing against the Detroit running game. No one on the DL had more than 3 tackles, they hardly made a play, but luckily the LB and more important safeties did make plays.
