Raiders offensive coordinator Greg Olson explains fourth-down failures

With the benefit of hindsight and some distance, Raiders offensive coordinator Greg Olson gave frank explanations Thursday of two key failed fourth-down plays against the Chargers on Sunday.
One came on the Raiders’ opening drive, on 4th-and-goal from the 1, when the Raiders ran a jet sweep to receiver Dwayne Harris for no gain.
“It was execution,” Olson said. The Chargers “lined up incorrectly, and at the last second, one of their defenders tried to run to get lined up correctly and that’s where our lack of execution occurred. They had three men; we anticipated two men to be to the side.
