These 2 Giants Signings Could Make Or Break Harbaugh's First Year

John Harbaugh banks on strategic signings like DJ Reader and Darnell Mooney to elevate the Giants' 2026 prospects.

Nearly half of the New York Giants’ 90-man training camp roster is new, and that kind of turnover usually means the spotlight lands on the obvious names. But if the Giants are going to make real progress in 2026, the quieter additions may matter just as much as the headliners.

According to Zachary Pereles of CBS Sports, wide receiver Darnell Mooney and defensive tackle DJ Reader are two under-the-radar players who could end up shaping the season. One is there to help stabilize a defense that got pushed around too often. The other could give the offense a much-needed lift if the receiver room thins out early.

Reader is the more straightforward fit. He is expected to start at nose tackle and step into the middle of the Giants’ defense as part of the effort to fix a run defense that finished last year at the bottom of the league in EPA per rush allowed. Pereles placed Reader 30th on his list, in the “Known face, new place” category, and wrote, “For all the excitement surrounding Year 1 of John Harbaugh, Year 2 of Jaxson Dart and two first-round picks, the Giants still need to figure out a way to stop getting run all over.”

Reader is not being asked to be Dexter Lawrence II, and the Giants know that. Nobody is.

But the 32-year-old veteran brings the kind of interior presence that can change the feel of a defense. Per PFF, he posted more than 20 run stops in three straight seasons before dipping slightly over the last two years with the Detroit Lions.

On a defensive line that is short on proven depth inside, he stands out as the most important piece.

Mooney landed much higher on Pereles’ list, coming in at No. 10 in the “Bounce-back candidates” group. Pereles said, “The Giants would love to see him get back to his 2024 form, when he showed a well-rounded skill set that hadn't been on display earlier in his career.”

There’s a path for that to matter quickly. The Giants are headed into camp with a crowded wide receiver room, which makes the depth chart hard to sort out right now.

Mooney’s familiarity with offensive coordinator Matt Nagy helps, and his ability to line up both in the slot and outside gives him a practical edge in the competition. If Malik Nabers is not ready to open the season, Mooney could be looking at a sizable target share.

The Giants will get plenty of attention for stars like Jaxson Dart and Abdul Carter. Still, the season can swing on players who don’t always dominate the headlines. Reader and Mooney fit that description, and both could wind up being central to whether the Giants reach their 2026 goals.

Giants Camp Battle Could Uncover An Undrafted Surprise Fans Will Watch

Training camp always has a way of turning the back end of a roster into one of the more interesting parts of August, and the Giants have a handful of undrafted players worth tracking as they sort out the final layers behind the starters. Dominic Zvada has moved into the lead at kicker, Ben Mann looks positioned to handle long-snapping duties, and the rest of the UDFA group is trying to carve out a place either on the 53-man roster or on the practice squad.

Damon Bankston is in the mix for one of those developmental spots at running back, while Ryan Schernecke and Jarrod Gray are both trying to prove they can survive the numbers game up front. On defense, Ben Barten and Anquin Barnes Jr. are battling the reality of a crowded interior line, and Barnes in particular has the look of a player who could force the staff to keep watching a little longer before deciding how many of these young hopefuls can actually stick.

Andrew Thomas Just Got Hit With A Brutal Giants Prediction

Andrew Thomas is still the Giants most important pass-protection piece as the team tries to settle Jaxson Dart into life as a starting quarterback. After a strong season that drew high marks from Pro Football Focus, Thomas has the kind of track record New York wants anchoring the left side, and he has already shown he can make life difficult for elite edge rushers when the matchup calls for it.

The concern, of course, is what happens when the schedule turns ugly and the Giants have to trust Thomas to hold up against one of the leagues most disruptive names. He has handled Myles Garrett well before, but the latest chatter around that matchup is less about Thomas rsum and more about how much punishment Dart might be asked to absorb when the pressure is at its peak.
