From Mark Sanchez and the offense to the defense to the special teams, the Philadelphia Eagles were outplayed and overmatched against the Green Bay Packers.

Dwelling on a miserable performance won't help.

"It's about coming back and not letting the same game beat you twice," coach Chip Kelly said Monday. "You can't feel sorry for yourself in this league. I don't know how that's going to make you any better."

Sunday's 53-20 loss to the Packers was the worst defeat in Kelly's two seasons and the third-most points ever scored against the Eagles (7-3). Moreover, it underscored several of the team's problems.

On offense, Sanchez made some poor throws. But the receivers dropped a few passes and the offensive line didn't block well. LeSean McCoy ran better than he did in a blowout win against Carolina last Monday, but the game was out of reach.

On defense, cornerbacks Bradley Fletcher and Cary Williams and the rest of the secondary were picked apart by Aaron Rodgers. The front seven couldn't generate pressure and gave Rodgers way too much time to throw.

Even special teams, who were Philadelphia's biggest strength, allowed a 75-yard punt return for a score.

"We lost as a coaching staff, as a special teams team, as an offensive team and as a defensive team," Kelly said. "It's not a finger-pointing operation. We all contribute to our wins and we all contributed to our losses."

Unlike their other two losses, the Eagles never had a chance at Lambeau Field. They trailed 30-6 by halftime on their way to their worst loss since Peyton Manning and the Broncos dismantled them in Week 4 last season 52-20.

In a 26-21 loss at San Francisco on Sept. 28, the Eagles had a chance to score the go-ahead touchdown but failed on two cracks from the 1.

In a 24-20 loss at Arizona on Oct. 26, the Eagles couldn't convert in short-yardage at the goal line and then allowed a long TD pass to blow a 3-point lead.

The Packers gave them a total beatdown from start to finish in all three phases. Green Bay's high-flying offense scored four TDs, defense had two and special teams got one.

"It's a wakeup call," linebacker Trent Cole said. "We need to get this off our minds, put it behind us and move on and win these next games."

The Eagles fell into a first-place tie with Dallas and have two games against the Cowboys in the next four weeks. But they can't overlook the Tennessee Titans, who were 2-7 entering Monday night's game against Pittsburgh.

"The only way to get that bad taste out of your mouth is to go out and play again," Kelly said.

The Eagles haven't had much success against good opponents under Kelly. They're 7-0 against teams with a combined record of 25-45-1. They're 0-3 against teams with a combined record of 22-8. Overall, they're 15-2 against teams .500 or worse and 2-8 against winning teams since 2013.

"Whether we win or lose, we look at the film and see the mistakes made and we have to improve," linebacker Connor Barwin said. "Obviously there were more mistakes and there's a lot to correct. If you lose by 30 or 40 or you lose by 3, it's still one loss in the column."

NOTES: Kelly said QB Nick Foles hasn't taken a new X-ray since breaking his collarbone two weeks ago. He'll get that test in another week or two and be re-evaluated. Foles has been cleared to run and workout.
