Sisi Mauigoa is quickly becoming a notable presence for the New York Giants as he nears the conclusion of his first professional training camp. Selected with the No. 10 overall pick in the 2026 NFL Draft, the 21-year-old offensive lineman has made a promising start in his transition from college offensive tackle at Miami to right guard in the NFL.

The Giants acquired the draft pick used to select Mauigoa in a trade that sent nose tackle Dexter Lawrence to the Cincinnati Bengals. The team views Mauigoa as a long-term solution at right guard, a position that has seen stability but also a recent change with Greg Van Roten, the veteran who started every snap at the spot over the last two seasons, now testing free agency. Mauigoa, at 6-foot-4 and 335 pounds, fits the profile the Giants envisioned—powerful, aggressive, and capable of anchoring their offensive line for years to come.

Throughout camp at The Greenbrier in White Sulphur Springs, West Virginia, Mauigoa has showcased the combination of strength and mobility required at the position. He plays between veteran right tackle Jermaine Eluemunor, entering his 10th NFL season, and center John Michael Schmitz, who is in his third year. This veteran presence provides the rookie with stability and mentorship as he adapts to the professional level.

Giants running back Tyrone Tracy commented on Mauigoa’s impact, stating that his presence on the field is notable and that he “moves people,” a key trait for both pass protection and creating running lanes. Linebacker Tremaine Edmunds highlighted Mauigoa’s strength during practice, while defensive tackle D.J. Reader praised the energy the young player brings to the team.

Head coach John Harbaugh stressed the importance of fundamentals for rookie offensive linemen, noting that footwork and competence are essential to avoid costly mistakes early in a player’s NFL career. Harbaugh acknowledged that it is rare for rookies at offensive line positions to immediately excel, but expressed cautious optimism about Mauigoa’s progress.

Former Giants offensive guard Chris Snee, a two-time Super Bowl champion and current senior scout, has been closely monitoring Mauigoa’s development during drills. Snee, who also played right guard as a rookie, serves as a key mentor and resource for the young lineman.

Mauigoa’s integration into the team appears smooth both on and off the field. His approachable yet competitive attitude has earned respect among teammates. For example, Andrew Thomas, the Giants’ left tackle, assigned Mauigoa the task of engaging fans with a pre-practice lap—a traditional “rookie duty”—which Mauigoa accepted without hesitation.

While Mauigoa is not expected to dominate immediately, the Giants are encouraged by his early showing and envision him as a cornerstone of their offensive line in the coming years. The team’s patience and commitment to his development could address their right guard needs well into the future.
