The Eagles have vowed to get better.
They desperately don't want to have a performance from their run defense like the one against Washington, when they gave up 230 yards on the ground.
Head coach Doug Pederson said the run defense is "a pride thing," and the guys responsible for the performance, Jim Schwartz included, say things will get better. The defensive coordinator cited bad angles as a reason there were so many missed tackles on Sunday afternoon.
In all, the Eagles missed 10 tackles and gave up 156 yards after contact — both more than they had given up in the first four games of the season.
Washington's rushing yards came in some big chunks. Here's a look at some of the key running plays from Sunday as we try to figure out what went wrong:
This is a key 3rd-and-7 from the Washington 13-yard line. On this drive, Washington ends up scoring a touchdown to go up 14-0, but it doesn't happen without this key third down conversion.
The Eagles collapse the pocket and force Kirk Cousins to his left. That's exactly what Schwartz said he wants, to force the quarterback to his non-throwing side. Everything at this point is working out perfectly.
Here's the angle that's really troublesome. At this point, Nigel Bradham (circled in green) has Cousins in his sights, while Vinny Curry and Brandon Graham (farther behind) are in pursuit. Curry and Graham seem to let up in their pursuit when it looks like Cousins will go out of bounds. But he doesn't.
Schwartz talked about bad angles and this is the perfect example from Bradham. He overshoots it, and when Cousins makes his cut back inside, all of Bradham's momentum is heading toward the sideline. Curry ends up making the tackle but tackles Cousins forward for a big first down.
This next play was just a little counter draw that ended up going for a huge 45-yard gain. Rob Kelley takes the handoff, which looks to be going right. The entire Eagles' linebacking group bites hard. Still, right end Connor Barwin is free and has a chance to make the play.
He doesn't. Just a missed tackle.
Kelley finds some open field. Rodney McLeod is the next guy to beat and Kelley simply turns him around. You'll see Mychal Kendricks enter the frame. Kendricks showed great recovery speed to get back in the play and has a chance to finally bring the running back down.
Nope. Can't do it. Eventually, McLeod recovers to bring him down.
This last play ended the game on Sunday. The Eagles punted the ball away with the hope that their defense would stop Washington and give them the ball back. Instead, Matt Jones broke off a 57-yard run on 3rd-and-7.
Jordan Hicks overpursues, probably thinking the run was going wide. But he loses his gap and Jones is off to the races.
Once Jones gets past the first down, it doesn't really matter that it was a 57-yard run. It could have been an 8-yarder and the game was over.
So what did we learn?
Well, Schwartz was right. Angles absolutely killed the Eagles on Sunday. But when they have a guy wrapped up, they need to bring him down. Sure, that's not earth-shattering, but they couldn't do it on Sunday and it led to a loss.
