PHILADELPHIA — The Giants offer Carson Wentz a chance to get back into the good graces of the Eagles’ notoriously fickle fans Sunday.

The No. 2 overall pick has slumped after a red-hot start to his NFL career, and Wentz will be looking to turn the page — and quiet the local grumbling — in his first brush with this bitter NFC East rivalry at MetLife Stadium.

“Obviously, it’s frustrating,” Wentz said Wednesday of his recent struggles. “We just have to execute down the wire. It’s pretty plain and simple — we can’t turn the ball over, and we just have to execute late in games. We’re just not executing right now.”

Wentz in a lot of ways is a victim of his own unexpected success.

Considered early on as a project so raw he might spend his entire rookie season on the bench, Wentz was thrust into the starting job just days before the season opener by Sam Bradford’s shocking trade to the Vikings.

Wentz promptly blew those low expectations out of the water, leading the Birds to a 3-0 start — including a shocking, 34-3 rout of the Steelers — while completing 65 percent of his passes with five touchdowns and no interceptions.

Philadelphia fans were ready to throw a parade for their prized new quarterback then, but both Wentz and the Eagles have fallen back to earth and enter Sunday’s game tied with the Giants for the second in the East at 4-3 after a 29-23 overtime loss to the Cowboys.

Wentz’s receivers dropped a staggering six passes in the Dallas defeat, offering further proof the Eagles have one of the worst receiving corps in the league.

Coinciding almost exactly with the start of Pro Bowl right tackle Lane Johnson’s 10-game PED suspension, Wentz also has been sacked 11 times in the past four games after suffering just four sacks in the first three contests.

But Wentz remains the one under the microscope in the wake of three losses in the past four games, belittled locally as “Captain Checkdown” after averaging 4.1 yards per pass attempt in the past two games — about half the average of your typical franchise quarterback.

First-year coach Doug Pederson, a former NFL quarterback, is also feeling heat for Wentz’s abrupt slowdown for what is considered to be overly conservative play-calling. The Eagles have just one play of more than 30 yards in a span of 230 offensive snaps the past four games.

Pederson defended that this week by noting Kansas City — where he was offensive coordinator in his previous stop — got off to a 9-0 start in 2013 by playing “small-ball.”

Pederson, though, admitted Wentz’s early success was an outlier and that his prized young passer is now on the track of ups and downs that is typical for a rookie quarterback as opponents get a better read on him.

Pederson insists he sees progress where others might see a lot of recent struggle. Even in the Eagles’ lone victory in that stretch, a 21-10 victory over the Vikings two weeks ago, Wentz committed three turnovers in the first quarter.

“The numbers may not be there [the past four games] … but he’s understanding how to spread the ball around and using his personnel a little bit better each week,” Pederson said. “He’s getting better there. So there are some things on the field and off the field that [may be] small, but they’re steps in the right direction.”

A Giants defense that ranks 22nd in pass defense offers Wentz a chance to rebound quickly, although the Eagles’ receiving corps is in turmoil after Josh Huff’s arrest Tuesday in New Jersey on gun and marijuana charges.

“Obviously, these division games are huge — for [me], especially, to kind of bounce back,” Wentz said of facing the Giants. “It was a tough loss last week, so I’m really looking forward to it.”
