The Las Vegas Raiders defense didn't produce as expected going into the off-season. Injuries and lousy execution started to pile up as the season progressed, especially in pressure situations.
One reason is that the Raiders could not stop offenses through the air. The defense was 31st in dropback EPA, according to RBSDM.com. The pass rush was Maxx Crosby or bust for most of the season, and the secondary was swiss cheese when quarterbacks had time.
Looking ahead to free agency, the Raiders will look to upgrade that position after losing players to one-year deals.
