OAKLAND, Calif. -- Observed in the locker room after the San Diego Chargers' 27-17 loss to the Oakland Raiders.

No excuses: San Diego coach Mike McCoy dismissed injuries or scheduling as an excuse for his team’s poor performance on the road, saying the Chargers need to come prepared to play each week.

“The parity is so good in this league that you’ve got to play your best every week,” McCoy said. “It comes down to you can’t turn the ball over five times and win many football games.”

Fourth-down woes: Trailing 14-0 with just over 10 minutes left in the first half, McCoy called for his team to go for it on fourth-and-1 from Oakland’s 1-yard line. The Chargers spread the field and ran Danny Woodhead up the middle, who failed to move the pile across the goal line. San Diego went into halftime down 17-0.

“I just thought it was a good opportunity for us,” McCoy said about the play. “They had all of the momentum in the game at that point of time. I think we had a good idea in the game. We had a run/pass check in there. Unfortunately they went blitz zero on us, and they made a play. I’d do it again tomorrow.”

Quarterback Philip Rivers said his team scored on a similar play against Tennessee on the goal line two weeks ago. Rivers said the Raiders disguised the blitz well.

“It was close,” Rivers said. “That’s one of those, too, where I’m not so sure he didn’t [get in]. He was close to getting in, but there’s a big pile there so you’re never going to see it.”

No answer for Pryor: San Diego made containing Terrelle Pryor a priority heading into Sunday’s contest. Yet they still allowed Oakland’s quarterback to consistently scramble outside the pocket and make big plays down the field, either with his arm or with his legs.

“He didn’t make many mistakes,” Chargers safety Eric Weddle said. “There were a few times where I could have baited him, and he never forced it in there. He’s shown that he’s gotten better in those situations. But when you turn the ball over five times and give up two easy scores like we did, you’re not going to win many games.”
