PHILADELPHIA — The last time the Philadelphia Eagles dominated the New York Giants like this, current Eagles punter Donnie Jones and long snapper Jon Dorenbos were babies and nobody else on the team was even born. Current coach Chip Kelly was a high school senior in New Hampshire whose first love was hockey.

The Eagles jumped all over the Giants en route to a 27-0 victory Sunday night at Lincoln Financial Field. It was the Eagles’ largest margin of victory over their long-time divisional rival since a 35-3 decision in 1980, and it was the first time they shut out the Giants since a 24-0 victory in 1996.

Adding injury to insult, Giants wide receiver Victor Cruz tore the patellar tendon in his right knee early in the third quarter. Cruz, whose season is over, spent the night in a Philadelphia hospital.

The win allowed the Eagles (5-1) to keep pace with the Dallas Cowboys for first place in NFC East. The Giants, who hoped to leave South Philadelphia with a share of first place in the division, headed back up the New Jersey Turnpike at 3-3 and in third place.

“This was a great team win for us because the offense and defense both played a solid 60 minutes,” said linebacker Connor Barwin, who had three sacks. “That’s what had been missing before. We’d play well in spots and the offense would play well in spots, but we didn’t put a total game together. Tonight, we did.”

The Eagles’ pass rush harassed Giants quarterbacks all night, sacking Eli Manning six times and backup Ryan Nassib twice. Manning was sacked just seven times in the season’s first five games. The strong defensive play gave the Eagles’ offense good field position for most of the game.

“It was nothing magical,” Giants coach Tom Coughlin said of the Eagles’ dominance. “They played hard and made things happen, and we couldn’t stop them.”

Eagles quarterback Nick Foles completed 21 of 34 passes for 248 yards, two touchdowns and two interceptions. All-Pro running back LeSean McCoy, who came into the game averaging just 54 rushing yards per game, had 85 yards by halftime and finished with 149 yards on 22 carries.

“Getting Shady (McCoy) going early was the real key to this game,” said Eagles tight end Zach Ertz, who scored the first touchdown of the game on a 15-yard pass from Foles. “He’s the focus of this offense, and when he gets it going like he did tonight, that just opens up the offense for everybody else.”

Manning finished 13-for-23 for 151 yards.

The Eagles took a 20-0 lead into their locker room at halftime, but a mistake by Foles early in the third quarter opened the door for a possible Giants comeback.

Foles threw a pass that was intercepted by cornerback Zack Bowman and returned 18 yards to the Eagles’ 21, but New York couldn’t cash in on the gift. The Giants pushed the ball to the Eagles’ 3-yard line, but wide receiver Victor Cruz couldn’t hold onto Manning’s fourth-down pass on the play on which he was injured.

And if things couldn’t get any worse for the Giants, the Eagles then drove 97 yards in just eight plays, scoring on running back Darren Sproles’ 15-yard sweep that made it 27-0. The Giants never threatened after that.

The Eagles really won the game in the first quarter, when they kicked a field goal and scored a touchdown on their first two possessions. Ertz’s diving catch in the end zone gave Philadelphia a 10-0 lead.

The Eagles made it 17-0 in the second quarter when Foles found tight end James Casey wide open in the end zone with 9:10 left in the period. Cody Parkey’s second field goal, this time from 45 yards, made it 20-0 with 4:25 left in the first half.

“I don’t know how you can explain a game like this, and I don’t think any of us can,” Giants safety Prince Amukamara said. “We had good practices all week, we were excited to come down here to play a divisional rival, and we just fell flat. The only good thing is that it’s just one game and we get to play another one next week.”

What the Eagles said:

“I made a couple of dumb mistakes with the football that I will work on. I can fix those things. They’re not over my head, and that’s one of the things I love about this game — you can fix things.” — Quarterback Nick Foles, who threw two interceptions.

What the Giants said:

“This is what happens when you play a good team and you play bad.” — Defensive end Jason Pierre-Paul.

What we learned about the Eagles:

1. Second-year tight end Zach Ertz is a potential star. He only caught three passes, but they went for 47 yards, and a per-catch average of 15.7 is excellent for a player in his position. Ertz also made a diving catch on his 15-yard touchdown reception in the first quarter. He has replaced veteran Brent Celek as the Eagles’ top pass-catching tight end.

2. Running back Darren Sproles was a key acquisition for the Eagles, who traded a fifth-round pick to the New Orleans Saints for the multitalented player. Against the Giants, Sproles rushed for 39 yards on seven carries, including a 15-yard touchdown run that gave the Eagles a 27-0 lead. Sproles came into the game averaging 15.9 yards per punt return, leading the NFL among returners with at least 10 attempts, He didn’t quite match that against the Giants, but he came close, averaging 14.3 yards, including a 43-yarder, before he left in the second half with a knee injury.

–RB LeSean McCoy, who came into Sunday night averaging just 54 yards per game and 2.9 yards per carry, had 85 yards by halftime, averaging 7.1 yards per carry. He finished with 149 yards on 22 carries, an average of 6.8 yards per attempt. QB Nick Foles thinks a big part of McCoy’s success was his approach. “He was hitting the lanes hard,” Foles said. “He wasn’t trying to bounce it (outside). If he felt like he didn’t have anything, he cut up inside for 3 or 4 yards. That really helps us out.”

–LB Connor Barwin didn’t enjoy the best game of his career, but it was close. The veteran had three sacks Sunday night, which is one below his career high, set against Jacksonville in 2011 when he was a member of the Houston Texans. Barwin, 27, joined the Eagles last year and has become one of the team’s defensive leaders. “When you have a game like this, it makes you feel young again,” Barwin said. “Really, a big key tonight was the way (defensive coordinator) Bill Davis moved us around. You could sense that they didn’t know where we were coming from and when we were coming, and if you can get a team on their heels like that, good things will happen.”

–The Eagles’ offensive line is finally holding its own. The line was hit hard by injuries and two starters — LG Evan Mathis and C Jason Kelce — are still sidelined. However, the Eagles have been bolstered by the return of RT Lane Johnson, who missed the first four games after he was suspended for testing positive for a performance-enhancing drug. Also, the two young players who replaced Mathis and Kelce, Matt Tobin and David Molk, respectively, are improving. “It’s still a work in progress, but we all feel better about where we are right now,” Johnson said. “And we should be getting (Mathis and Kelce) back soon, maybe even after (next week’s) bye. We’ve struggled at times this season, but things are definitely looking brighter now.”

What we learned about the Giants:

1. New York added skill players such as running back Rashad Jennings and rookie wide receiver Odell Beckham Jr. this season, but that won’t mean much if the line can’t do a better job protecting quarterback Eli Manning than it did Sunday night. Manning was under duress much of the night and was sacked four times in the first half as the Eagles built a 20-0 lead. Giants quarterbacks were sacked a total of eight times in the game, with offensive tackle Justin Pugh giving up three of them.

2. Rookie running back Andre Williams, who started in place of injured Rashad Jennings (knee), might be a good player somebody, but he has a long way to go. He ran hard but missed holes several times and seemed more concerned about protecting the ball than gaining yards. He also needs work at pass protection against the blitz to get more playing time when Jennings returns.

–As upset as the Giants were by getting blown out on Sunay night, they were even more upset that WR Victor Cruz was lost for the season with a knee injury sustained in the third quarter. “He’s such a big part of who were are, on the field and in the locker room,” Giants TE Larry Donnell said. “He brings so much energy and he’s one of the best play-makers in the league. But mostly I feel bad for him, because I know how much he loves to play and how much he loves being a New York Giant.” Said DE Jason Pierre-Paul: “We’re going to keep him in our prayers. But it’s a tough loss and someone else has to do the job that he does for us.”

–The offensive players seemed to be at a loss for words in trying to explain how they played so poorly Sunday night after putting together three strong games in a row. However, it was obvious what the problem was: Every time the Giants started to move the ball, they made a critical mistake. “We’d have a first down or have a little momentum, and then just kind of got a bad play,” QB Eli Manning said. “We’d have a sack or penalty and then we’d get stuck in third-and-very-long.”

–One reason the Giants won three straight games was the play of RB Rashad Jennings, who was deactivated because of a sore knee. Jennings was the fourth-leading rusher in the NFL coming into the game, with 396 yards. His replacement, rookie Andre Williams, rushed for 16 yards on 58 carries in his first game against an NFC East rival. “I guess you could call it a rude introduction,” Williams said. “We just didn’t execute the way we wanted, and you’ve got to give it up to the Eagles defense.”
