In the weeks before training camp, we’ll break down each position on the Giants roster to highlight the team’s strengths, weaknesses and the depth-chart battles that will determine who’s around for Week 1:

Returning players: Jason Pierre-Paul, Johnathan Hankins, Kerry Wynn, Jay Bromley, Owa Odighizuwa, Montori Hughes, Louis Nix, Stansly Maponga

Key newcomers: Olivier Vernon (free agent), Damon “Snacks’’ Harrison (free agent)

Assessment: A return to health for two players and two expensive free-agent acquisitions have the Giants thinking big here. Potentially, this could be a formidable group that gets the defense back in business. They hope “you get what you pay for’’ rings true after writing contracts worth $85 million for Olivier Vernon (from the Dolphins) and $46.25 million for Harrison (former Jets nose tackle).

In 2015, the Giants’ defensive line produced a measly 19 sacks, and the players who totaled 18 of those sacks are no longer with the team. Jason Pierre-Paul, remarkably, played in the last eight games after his recovery from nearly blowing off his entire right hand in a July 4 fireworks accident. Pierre-Paul could not grab hold of anything wearing a bulky protective club, and the expectation is a newly designed four-fingered glove will greatly enhance his ability to pull down ball-carriers. He is in phenomenal shape, on a contract year and only 27 years old, so this is a huge season for him.

Vernon cannot possibly live up to his mega-deal, but the Giants see him as an ascending 25-year-old defensive end with impeccable health and work ethic. The most sacks he’s had in a season: 11.5, in 2013. Harrison is a first-rate run-stuffer, but the Jets did not want to pay so much for a two-down player. The Giants allowed 121.4 yards per game on the ground last season, and thus the need for “Snacks’’ arose. The loss of Hankins in 2015 to a torn pectoral muscle after eight games was a crushing blow. He was developing into an excellent all-around interior lineman. Owa Odighizuwa, a 2015 third-round pick, gave the Giants nothing as a rookie other than injuries. They envision him as a pass-rusher. It is a year of decision for tackle Jay Bromley (third round, 2014), who has not made much of an impact in two seasons as a reserve.

Camp battle to watch: There is no way Odighizuwa is going to get cut, but his upcoming battle is to fortify a spot in the playing rotation. Built like Adonis, Odighizuwa struggled with foot and hamstring issues as a rookie and ended up playing in only four games before landing on injured reserve. In truth, he showed nothing. He is a high draft pick and made plays at UCLA. The Giants need him to prove in camp and in the preseason games that he means business in year No. 2.
