exclusive details New York Giants Paul Schwartz John Harbaugh’s stacked offensive Giants staff has plenty of experience — and no ego By Paul Schwartz Published Aug. 26, 2026, 8:09 p.m. ET Giants head coach John Harbaugh gives a fist bump to wide receiver Darius Slayton during football practice on Aug. 25, 2026, in East Rutherford, N.J. Noah K. Murray-NY Post Here is the thing about John Harbaugh: He is not in the building and on the practice field to coach the players and call it a day. He is on the scene to coach everyone, and that includes his staff.
Not every head coach — even one who spent the past 18 years with one franchise, winning a whole lot more than he lost — would have had the self-assuredness to bring in who he brought in. The guys he hired and entrusted with his offense are big-timers, in terms of skins on the wall in the NFL, and there is certainly a possibility that this mix of brainpower could lead to a too-many-cooks-in-the-kitchen scenario.
