This could be a problem that the Pat's expose.
"His biggest issue came in pass protection, where he ended the game with a lowly 11.8 PFF grade after surrendering five total pressures. The volume of pressure wasn’t as big a problem as the type of pressure allowed, with multiple decisive and near-immediate losses causing problems for the Raiders’ offense.
In addition to those pressures, there were also five clean losses in pass protection where the ball came out before it could become pressure on Derek Carr. Simpson fared better in the run game, which isn’t to say well. He was beaten for three tackles, all of which were defensive stops, and was routinely struggling to make headway against the Saints’ defensive linemen."
