OAKLAND, Calif. - At least the Eagles' offensive and defensive players seemed to be in agreement about why they left the Oakland Coliseum late yesterday afternoon with one of the more shameful losses of coach Andy Reid's tenure in Philadelphia.

"When you lose, especially in this fashion, you can point your finger at a whole bunch of stuff," running back Brian Westbrook said after the Eagles failed to score a touchdown in a 13-9 loss to the Oakland Raiders, a team that had been publicly humiliated and ridiculed by the New York Giants seven days earlier.

But Westbrook, despite his best game of the season, said the offense most deserved the blame for this blundering performance.

"We didn't run the ball good enough, we definitely didn't throw the ball good enough, and we didn't block good enough," the veteran running back said. "We're better than that. We didn't execute our offense very well at all."

It's impossible to argue the point, and some of the Eagles' defensive players didn't even try.

"You give up 13 points," cornerback Sheldon Brown said with a shrug. "Our goal has been to hold teams under 17 points ever since I've been here and we did that. It's just one of those damn dreams and we're still dreaming it."

Asante Samuel, the Eagles' other starting cornerback, seemed to agree with Brown.

"Thirteen points, you're supposed to win the game," he said. "But we didn't make the plays to win."

There's no getting around the fact that it was a dreary day for the Eagles' offense, which was once again grossly unbalanced in favor of the pass against Oakland, which was ranked 31st against the run coming into the game.

Quarterback Donovan McNabb completed 22 of 46 passes for 269 yards and was sacked six times. When you figure in the sacks and two scramble runs by McNabb, the Eagles called 54 pass plays and just 12 running plays.

"In hindsight . . . you would love to run the ball a whole lot more," Westbrook said. "You'd love to control the ball a whole lot more. We've had a lot of success throwing the ball in the first four games, so it's hard to go away from that, but looking at it, we had success running the ball."

Westbrook ran six times for 50 yards, an average of 8.3 yards per carry. He also caught nine passes for 91 yards, but there were pivotal times in the fourth quarter when he wasn't even on the field.

"That's the way coach is doing it now," Westbrook said. "Me and LeSean [McCoy] are switching series."

For his part, Reid had little to say. He walked out of his news conference after a little more than three minutes, which allowed him to avoid some of the more difficult questions about his inept offense. His team is now 3-2.

"They blocked better, they tackled better, and I thought they blitzed better," Reid said. "They did it all and they coached better."

Eight of the Eagles' 14 offensive series ended in a punt, and nine of them were over after five plays or fewer.

"I'm embarrassed with the way we played," McNabb said. "We're a much better football team than that. It won't happen again."

Defense and special teams didn't deserve a pass for this unsightly mess.

Two of the Eagles' offensive series ended with missed field goals by David Akers. He pushed a 45-yard attempt wide left in the first quarter and pulled a 47-yard attempt wide right at the end of the Eagles' first offensive possession of the second half.

Akers was not around to discuss the missed kicks after the game.

The defense, meanwhile, had some positive moments - Samuel had an interception that led to a squandered scoring opportunity in the first quarter, and safety Quintin Mikell helped set up a second-quarter field goal with his first interception of the season - but giving up 13 points to quarterback JaMarcus Russell and the Raiders' offense is nothing to pound your chest about. Oakland had scored a total of 16 points in its previous three games. The defense also surrendered 209 passing yards to a team that had been averaging 108 per game.

Middle linebacker Jeremiah Trotter had as bad a day as his offensive teammates.

After the Eagles scored on a field goal to take a 3-0 lead in the first half, Trotter bit on a play-action fake by Russell and was burned by tight end Zach Miller, who turned the play into an 86-yard touchdown reception.

"I have to do a better job reading and reacting to the run and pass," Trotter said.

His more costly mistake came at the end of the game when the Eagles needed the football back for a chance to overcome their afternoon of missed opportunities.

Faced with a third-and-10 situation, Russell flipped a pass to fullback Gary Russell, who beat Trotter for a 13-yard gain that allowed Oakland to run out the clock and celebrate its second win of the season.

Trotter was only on the field because middle linebacker Omar Gaither had twisted his ankle.

"I felt like I took two steps backward," Trotter said of his second game since returning to the Eagles. "It's just frustrating to lose a game we definitely should have won."
