Khalil Mack must've been licking his chops to play the Pittsburgh last weekend.
The Steelers licked Mack instead. Against a line down two regular starters, they completely blanked the second-year linebacker off the final box score.
Marcus Gilbert and David DeCastro mauled Mack all afternoon. The end result? No tackles, no sacks, and only four quarterback hurries in a game Ben Roethlisberger attempted 44 passes in.
He rarely fared better against the run. While the Steelers mostly avoided his right side, reserve running back DeAngelo Williams carved his defense up to the tune of 170 yards.
The Raiders expected more. They're getting solid contributions from Aldon Smith and Mario Edwards Jr. up front, but not much else from their supposed star rusher.
