Not only did Oakland practically run San Diego out of its own stadium, but there were enough Raiders fans to make it feel almost like a home game.
"That's the longest we have sustained really good football as a team in all three phases," first-year coach Jack Del Rio said. "I'm really happy for our guys."
Veteran safety Charles Woodson said allowing 23 points in the fourth quarter "was almost like a blueprint for how not to finish games."
Del Rio didn't seem perturbed about that.
"That's not going to be the focus. The focus is going to be that we got a win that we needed," Del Rio said.
Cooper, the first-round draft pick out of Alabama, caught a short pass from Carr on an inside screen and raced through the defense to give the Raiders a 30-3 lead just before halftime. He finished with five catches for 133 yards.
"Coming out of the bye was big for us to come out hot, come out rolling," Carr said.
"It was sickening in how fast it happened," said Rivers, who was coming off a 503-yard performance in a gut-wrenching, 27-20 loss at Green Bay the previous Sunday. "Shoot, it was 30-6 at halftime."
Said coach Mike McCoy: "It was poor all around. It's pathetic. That first half was pathetic. No excuses it starts with me. Put it on me."
Sebastian Janikowski kicked the first of his three field goals, from 29 yards, and Carr found Walford for an easy 23-yard score and a 17-3 lead early in the second quarter.
"I think we need more touchdowns," Carr said. "Field goals aren't enough in this league. We had a lull. That's where inexperience kicked in, where I have to do a better job on staying on the guys about finishing."
The Chargers played without star tight end Antonio Gates (knee) and safety Eric Weddle (groin), and rookie running back Melvin Gordon was benched for the first half, apparently more punishment for his two fumbles in a gut-wrenching 27-20 loss at Green Bay. Gordon was benched for the second half of that game after losing one of the two fumbles. He has lost three of four fumbles this season.
The Chargers' future in San Diego is uncertain. They walked away from negotiations with city and county officials for a new stadium in mid-June and have been focusing on getting to Los Angeles. The Chargers and Raiders apparently were spooked into action after St. Louis owner Stan Kroenke announced plans for a stadium in Inglewood.
