Wonder how the Giants will be this year. 🤔"Looking good so far," wrote another."Promising start," added another.More reactions poured in."Giants fans eager to see his development," wrote one user."I think he got mad Potential," wrote another."Not that great," added another.Jaxson Dart took snaps behind a second-unit offensive line featuring Joshua Ezeudu, Aaron Stinnie, Austin Schlottmann, Jake Kubas and Marcus Mbow. Left tackle Andrew Thomas, still on the physically unable to perform list, did not suit up.The moment held personal weight for Dart, not just because it came in the stadium where reigning NFL MVP Josh Allen has built his career but because Allen himself had offered advice earlier this offseason.The two connected shortly after the draft, with Allen stressing the importance of leadership and earning the trust of teammates."He talked a lot about leadership," Dart said, according to Giants.com. "That was kind of like his main thing and then trying to be the best teammate for the guys around you because as a quarterback, you have to raise the standards of everybody."Coaching staff confident in Jaxson Dart's development timelineNFL: New York Giants Training Camp - Source: ImagnInside the Giants’ building, coaches say Jaxson Dart has been progressing as expected.

Saturday’s game marked the first real-time test of that preparation.
