NEW YORK — John Harbaugh stacked his new Giants staff on Friday with a ninth coach in the strength and conditioning department.

Sam Rosengarten is following Harbaugh to New York from the Ravens to become the Giants’ new “director of high performance,” the same title he held in his ninth and final season in Baltimore.

This is an interesting title because it sounds similar to Aaron Wellman’s. Wellman is the Giants’ “executive director of player performance.” Harbaugh already announced he was retaining Wellman from the previous staff.

The team website still lists Wellman at the top of the Giants’ “strength and conditioning/performance” hierarchy, though, with Rosengarten as second-in-command and Ron Shrift — another Harbaugh Baltimore hire — on board as the “director of strength and conditioning.”

In addition to Rosengarten, Harbaugh hired five football analysts on Friday: Skyler Mornhinweg, Taylor Kolste, Patrick Moynahan, Kyrell Michael and Bonner Bordelon. Mornhinweg is the son of longtime NFL coach Marty Mornhinweg.

Harbaugh’s nine-man strength staff now includes six holdovers and three new hires.

Wellman, assistant strength and conditioning coach Chris Allen, performance manager/assistant strength and conditioning coach Sam Coad, director of performance nutrition Matthew Frakes, assistant strength and conditioning coach Mark Naylor and assistant director of strength and conditioning Drew Wilson are back.

Rosengarten, Shrift and assistant strength coach Brian Ellis are all new.

The evolution of this crowded staff will be interesting to watch. Harbaugh’s turnover of the building included a major shakeup in hiring new head athletic trainer Adam Bennett from the University of Miami, with Ronnie Barnes moving out of his longtime position to continue overseeing medical services in some capacity, per the team.

Rosengarten has nine seasons of NFL experience, all with the Ravens. He held the same role in Baltimore, where he oversaw player monitoring systems, training load management, recovery protocols and performance analytics.

The Giants say he “integrated real-time biometric monitoring during practice, advanced player‑monitoring protocols and injury‑prevention strategies tailored to the demands of the NFL.” And “his expertise helped shape new data applications within the organization, driving innovation in injury forecasting and personalized athlete development to enhance player availability, optimize performance and support overall team success.”

Before arriving in Baltimore, Rosengarten led the Buffalo Sabres’ injury‑prevention program for two NHL seasons and oversaw all day‑to‑day care of the players. He also has consulted previously for the New York Knicks and Oklahoma City Thunder.

He seems to arrive with the credentials and title of someone who will one day run this department. For now, he is a part of a crowded collaboration as the Giants forge ahead and attempt to improve all operations.
