‘Specifically, the Bills need to be better against the run (16th) and in points allowed (18th), but taking it a step further, Pro Football Focus sees loads of room for improvement. In their advanced metrics, PFF graded the Bills as the 13th-best overall defense in the league (a far cry from second based on yards only), but had them 23rd against the run and 29th in tackling. Against the pass, PFF ranked Buffalo 10th in pass rush efficiency and ninth in coverage efficiency.’
