The Oakland Raiders won only four games this past season, as they really struggled to play consistent football on both sides of the field. In particular, the defensive backfield was slow to hit their stride in 2018, and while they played better late on, they were torched way too often this season.
Pro Football Focus recently released their final rankings for all 32 teams in terms of their secondaries, and the Raiders came up just short of the cellar. The outlet ranked the Raiders secondary as the 31st-best unit in the league, which is short for saying that they were nearly the worst in the NFL.
