The Giants have added Chargers quarterback coach Shane Day to their list of candidates for their offensive coordinator vacancy. He will interview for the job on Saturday, according to NFL insider Jordan Schultz.
Day, 51, joined the Chargers in 2024 on Jim Harbaugh‘s new coaching staff. He would be staying in the family if he gets the job in New York under Jim’s brother, John Harbaugh. But unlike most of the recent hires to the Giants’ coaching staff, Day has no direct connection to John Harbaugh himself.
Instead, Day has held a variety of roles with six different NFL teams in the last two decades, as well as brief college stints at Michigan and Connecticut. He was the quarterbacks coach for the Bears (2010-2011), 49ers (2019-2020), and the Chargers (2021-2022, 2024-present). Across his career, he has worked with Jay Cutler, Jimmy Garoppolo, Justin Herbert, and C.J. Stroud, among others.
Day was particularly instrumental in developing Herbert. He arrived in Los Angeles in Herbert’s second year in the NFL, in which he became one of three players to eclipse 5,000 passing yards since 2020. Herbert put up another strong year in 2022, saw a dip in 2023, and rebounded in 2024 and 2025 working with Day once more.
The success of Day’s partnership with Herbert is likely one of the main reasons for the Giants’ interest in hiring Day. They will be hoping that 2025 first-round pick Jaxson Dart can take a leap in his first full season as a starter, and Day could be the coach to pull that out of him.
However, Day has never called plays for a college or pro team. He would have those responsibilities under Harbaugh in New York, so hiring him could be a bit of a gamble. It might be worth the risk, though, if Day can take Dart to the next level.
