In one half, it looked like a team, or more specifically an offense, still shaking off the rust from a bye week. In the next half, it looked like the same team that has dominated the NFC for the entire season.
To the tune of a 30-0 score in the final 30 minutes, the Eagles rolled to another win, defeating the Cowboys, 37-9, on Sunday night in Dallas.
Here are this week's grades.
Pass Offense – B
The Eagles offense in the first half was not good. Carson Wentz looked off and shaky on some of his passes. Receivers were dropping passes. The running game couldn't get going.
After an opening drive that resulted in a touchdown, the Eagles offense was stagnant and in trouble. There were points that weren't taken in spots where they needed to be had, like after Rodney McLeod's interception in great field position that resulted in a missed field goal by Jake Elliott.

But in the second half, well, what a difference. Wentz wasn't really dominant, but he recovered nicely and certainly put together an excellent performance in the second half. Through the struggles, he protected the ball. There were no interceptions, no turnovers and, credit to the offensive line, no sacks.
Alshon Jeffery was tremendous in that second half with some of the catches he made. The Eagles got plays in all forms really in the half and while it wasn't really in the passing game that they shined, they did so much to separate themselves from the Cowboys and the rest of the NFC for yet another week.
Run Offense – A
Running backs, take your pick.
Jay Ajayi didn't score, but unleashed a 71-yard run that nearly went the distance and led the team with 91 yards. Corey Clement was excellent again with another touchdown. LeGarrette Blount continued to be serviceable and even picked up 30 yards on one big carry of his own.
But this unit isn't defined by individuals. This is a rotation that is becoming so consistent and dominant in games, it's scary.
In total, the Eagles rushed for 215 yards and two touchdowns. They are as good as it gets in football right now.
Pass Defense – A
If Eagles-Cowboys games are highlighted as Wentz-Dak showdowns, then Wentz won this one and not just because of the score.
Dak Prescott had a few moments, but the Eagles were able to sack him four times and create four turnovers against him. Three interceptions allowed the Eagles to never really let the Cowboys get into dangerous field position. Derek Barnett forced the fumble on a sack and it was recovered and returned for a touchdown by Nigel Bradham.
Ronald Darby had one of those interceptions in his return, and looked really good in this game. It's hard to say the Eagles missed him when they have performed so well all season, but you certainly saw how Darby can be a difference maker for this team. In addition to the interception, Darby led the team with eight tackles.
Make no mistake, the Eagles pass defense exposed the Cowboys big time in this game. While the Eagles offense struggled in the first half, the Cowboys really did no better and settled for three field goals. In the second half, this group was essentially flawless.
Run Defense – B+
Without Ezekiel Elliott, the Cowboys still got 91 rushing yards from Alfred Morris and 112 total rushing yards, not the insanely low totals we are used to seeing from the Eagles.
But Dallas really tried to incorporate the run as much as possible, with 27 carries for the game, and still managed just 4.1 yards per carry in the game.
Special Teams – C+
It's hard to give this one a true grade.
Allowing the Cowboys to run back the opening kick for 61 yards was basically the reason Dallas even got on the board first. When Jake Elliott missed the 34-yard field goal that would have essentially been a gift from the Dallas offense was brutal, so not a good start at all for this group.
But give Kamu Grugier-Hill a ton of credit for being a stand-in kicker and doing a fair job in at least making sure kickoffs didn't come out too far. Losing Elliott with a head injury was costly, putting the team without a place kicker for the rest of the game and forcing them to go for two points after every touchdown — the Eagles were 3-for-4 on those.
Realistically, it wasn't the Eagles best special teams showing. It just hardly mattered as the score got more and more out of hand.
Overall – B+
Yes, the Eagles just dropped 37 points and a 28-point margin in a game that could be graded a B+ at best.
What this team was able to do from one half to the next was nothing short of amazing. The Eagles trailed at halftime. They couldn't get anything going offensively. There was no rhythm, the sharpness wasn't there, the communication didn't seem to be there. It was really a disaster of a first half without being so far behind on the scoreboard.
That was probably the Eagles saving grace. In a game where the offense took a while to warm up, the defense held the Cowboys at bay.
This is why we have to look at this team differently than in the past. It's always been offense and passing and running and weapons for Wentz. This is a really, really good defense. This is a team that managed to make adjustments and remain positive at halftime to deliver in the second half. This is a team that has a big future ahead this season.
Why is that? This win basically sealed up the division. The Eagles are up four games on their NFC East counterparts with a 9-1 record. You might want to get ready for a home playoff game in January. It's coming.
But there's still work to be done. The Eagles turned in a great game with a performance that really wasn't their best. There are tough opponents that wait down the stretch before the playoffs that will serve as a litmus test for where this team stands.
But for now, one thing is for sure. The Eagles will have a winning season this year, and probably a whole lot more.
