Saturday night's regular season home finale called for the Eagles' defense to be at its best, but with playoff hopes on the line, the defense came out flat against Washington in a 38-24 defeat.

"It's a tough feeling," said linebacker DeMeco Ryans. "We knew it was all on the line today and for us not to show up and not play our best is disappointing. We didn't cover well. They made plays on us. They do a good job with the play-action, but that's no excuse. We have to cover better. We've been so up and down. We've had sloppy plays and it's just not good enough."

The Redskins totaled 418 yards of total offense, with 351 coming through the air. Redskins quarterback Kirk Cousins continued his impressive play during the second half of the season, throwing for 365 yards and four touchdowns in a commanding performance.

"It's on us because we didn't make plays," said defensive end Fletcher Cox, who added two more sacks to his career-high total of 9.5 for the season. "They made more plays than we did tonight and won the football game."

Throughout the season, the Eagles have failed to put things together consistently on both sides of the ball. Saturday night was no exception, and although players like safety Malcolm Jenkins believe there is plenty of talent inside the locker room, coming together as a team continues to evade the 2015 Eagles.

"It's very, very frustrating," said Jenkins. "I thought that we played hard and for whatever reason it's just not coming together on gameday.

"I look at the roster and the guys we have in the locker room and we have guys that can play, but for whatever reason, as a cohesive unit we're not that good. Everybody in this organization has a hand in that and we just can't figure it out … With the division on the line, especially at home, there's nothing worse than that -- to lose at your house and have them clinch the division at your stadium."

Defensive coordinator Bill Davis echoed Jenkins' thoughts as well, saying that the whole team needs to find a way to improve and that the personnel inside the locker room isn't the problem.

"We need to do better as a team," Davis said. "It wasn't just one position or one group. As a whole unit, we didn't play well enough to win, and they did.

"It's awful. I mean this is the last place we wanted to be, but this is where we find ourselves. We'll look hard at everything and everybody and everything we're doing, and we'll ask ourselves why it's happening and we'll do our best to fix it going into next week."

With Saturday's loss, the Eagles have officially been eliminated from playoff contention. While a Super Bowl in 2015 may not be a possibility, this Eagles defense still has plenty to prove in next week's season finale against the New York Giants.

"We've got to get it fixed and we've got to figure out the whys and hows and solve the problem," said Davis. "As team we need to make sure that we hang together and take all the accountability that we need to. The City of Philadelphia, we've got to give them better. I've got to do a better job and everybody's got to look at themselves and do a better job."
