Defensive Line: F+
When LeVeon Bell is out and you STILL give up 170 yards rushing and two touchdowns, there is a problem. This group had only two tackles for a loss and one sack. Granted, that sack was a huge play by Aldon Smith that knocked Ben Roethlisberger out for the game and forced a punt. That is basically where the + comes from.
The linebackers were better than the defensive line and Malcom Smith made a couple of great tackles at the goal line on DeAngelo Williams. But overall, they were horrific against both the pass and the run.
Antonio Brown is arguably the best wide receiver in the NFL. But 17 receptions for 284 yards is pretty ridiculous. The Steelers made the Raiders secondary look like a youth football team and the only positive really came when David Amerson picked off Ben Roethlisberger. Other than that, this was an embarrassing performance that cost the Raiders the game.
Defense Overall: F
It is very hard to win ball games when you allow 38 points. Even harder when just one of their receivers manages almost 300 yards receiving in the game and their backup running back rushes for nearly 200 yards. Despite this, Derek Carr and the Raiders offense still had the Raiders in the game with a minute left only to watch the defense blow the game.
Special Teams: F
If Taiwan Jones doesn't fumble that ball, the Raiders win, simple as that. To make matters even worse, Marcus Thigpen decided he would fumble too. Both fumbles were recovered by the Steelers.
