The Post’s guide to the 2016-17 NFC East the Giants will face this season.

Dallas Cowboys

Coach: Jason Garrett (seventh season)

Biggest newcomers: Jerry Jones was conspicuously quiet in terms of his roster this offseason — especially after a 4-12 disaster. The most prominent addition was first-round pick Ezekiel Elliott, a talented RB from Ohio State. Why Jones didn’t pursue a veteran backup QB with Tony Romo’s fragile collarbone just a hard shot from ruining another Cowboys season remains a mystery.

Biggest losses: On the plus side for Dallas, their roster didn’t suffer many notable defections, either. Jones jettisoned volatile DE Greg Hardy, but that probably will end up being a case of addition by subtraction. G Mackenzy Bernadeau, a middling talent, left for the Jaguars in free agency.

Camp outlook: When moving into a glitzy new practice facility is the biggest highlight, you know it’s been a rough offseason. The start of camp couldn’t come fast enough for the Cowboys after an ugly winter and summer filled with injury concerns and discipline matters.

The defensive front seven will start the season in disarray, thanks to NFL suspensions of LB Rolando McClain and DEs Randy Gregory and DeMarcus Lawrence that came in rapid-fire succession last month.

But Romo is by far the biggest worry, coming off repeated collarbone injuries and surgery that caused him to miss all but four games last season — the primary reason Dallas slumped from 12-4 to 4-12. The only backups are Kellen Moore, who went 0-2 while completing just 59 percent of his passes last year, and rookie Dak Prescott, a read-option quarterback at Mississippi State.

How they fared vs. Giants last season: The teams split the series 1-1.

Philadelphia Eagles

Coach: Doug Pederson (first season)

Biggest newcomers: Pederson is a coaching unknown and curious choice to replace the axed Chip Kelly. Player-wise, the Eagles caused one of the biggest commotions of the offseason, mortgaging their future to take QB Carson Wentz No. 2 overall out of North Dakota State. The Wentz move was controversial, coming just weeks after Philadelphia gave Sam Bradford a lucrative new deal and signed veteran backup passer Chase Daniel. Other key additions include G Brandon Brooks (Texans), S Rodney McLeod (Rams) and ex-Giants WR Rueben Randle.

Biggest losses: After Kelly was fired, newly re-empowered GM Howie Roseman wasted no time in putting his mark on the franchise, trading RB DeMarco Murray to the Titans and LB Kiko Alonso to the Dolphins. Murray was a bust in his lone season in Philly, and the Eagles still have Ryan Matthews and Darren Sproles in the backfield.

Camp outlook: Change is in the air for the Birds after three years of Kelly’s unorthodox stewardship, that included missing the playoffs in the past two seasons.

The roster is thin, especially at wide receiver and throughout a defense that ranked third-worst in the NFL last season. But all of the focus in camp — and no doubt beyond — will be on the Eagles’ extremely crowded quarterback situation. Bradford already has shown his displeasure with Wentz’s arrival by boycotting part of the offseason workouts, and the team’s talk of giving Wentz a redshirt year seems far-fetched based on the high price it paid for him and the pressure it is facing to win now.

How they fared vs. Giants last season: Philadelphia swept the series 2-0.

Washington Redskins

Coach: Jay Gruden (third season)

Biggest newcomers: What had been an uncharacteristically quiet offseason for Washington blew up in May, when they swooped in to sign Pro Bowl CB Josh Norman after the Panthers suddenly decided to lift his franchise tag. The Redskins also fortified their defense by signing ex-Broncos S David Bruton and added depth at tight end with former Broncos and 49ers TE Vernon Davis.

Biggest losses: His incredible flameout with the Redskins finally complete, Robert Griffin III is now in Cleveland. That won’t be considered a detriment by Gruden, who never warmed to the mercurial quarterback. The only other prominent departure was by DT Terrance Knighton, who signed with the Patriots.

Camp outlook: The surprise Norman signing sent a jolt of adrenaline into the Redskins and could make them the favorite to repeat as division champions.

But that is assuming QB Kirk Cousins continues the sudden improvement he flashed at the end of last season — a big question even to the team’s management, which refused to sign him to a long-term extension in the offseason.

As Cousins goes, so go the Redskins.

How they fared vs. Giants last season: The teams split the series 1-1.
