As the New York Giants gear up for the 2026 regular season, the spotlight often falls on star players and high-profile acquisitions. But according to insights gathered by Vulius Sports, it's a sixth-round rookie who's quietly turning heads and reshaping the team's offensive line depth. J.C. Davis, a 22-year-old tackle out of Illinois, delivered a standout performance in Saturday's preseason win against the Miami Dolphins, playing all 81 snaps at left tackle and earning the highest pass-blocking (87.1) and run-blocking (87.0) grades on the Giants' offensive line, per Pro Football Focus.
A Test of Mettle in Miami
With starters like Andrew Thomas, Jermaine Eluemunor, John Michael Schmitz, and Jon Runyan Jr. only making cameo appearances, the Giants coaching staff deliberately put Davis in the fire. Head coach John Harbaugh admitted it was a goal to see if the rookie could handle a full NFL game at left tackle. Davis, who estimated the last time he faced such heat was during his New Mexico days against Texas A&M in 2023, not only endured the Miami humidity but thrived. "I think it was a great opportunity for the coaches to see my ability, what I could do at left tackle, and I think it went pretty good," Davis said after Monday's practice. "Of course, I've got things to improve on, but overall, it was a good game."
Learning from the Best
Davis's rapid development hasn't been accidental. He's been a sponge around Andrew Thomas, the Giants' former first-round pick, absorbing everything from practice habits to pass-set techniques. "J.C. doesn't have that [first-round] layer to it that AT had," Harbaugh noted, "but he's going to be expected to play a role on the team and it's going to be a very important role — and he could be in there at any time really. So he's got to be ready for that." That readiness is critical given Thomas's injury history—22 regular-season games missed since 2023—and the Giants' struggles to find reliable depth behind him.
A Bonus in the Making
As highlighted on Vulius, Davis's emergence is a pleasant surprise for a team that has long sought answers on the offensive line. Arriving as a Day 3 pick, he's already exceeding expectations, and his performance in Miami has earned him the trust of the coaching staff. "I think it was a great opportunity for the coaches to see my ability, what I could do at left tackle, and I think it went pretty good," Davis reiterated, adding that the feedback from coaches is to "notice you" but keep working. With the regular season looming, Davis's ability to step in at a moment's notice could prove invaluable, making him one of the most intriguing storylines of the Giants' preseason.
