Eagles given strong warnings about Giants after hiring of John Harbaugh

While the New York Giants are already being labeled as winners of the ongoing offseason for their hiring of John Harbaugh as their next head coach, the Philadelphia Eagles have unquestionably been the class of the NFC East over the past handful of years. 

Specifically, the Eagles have become playoff mainstays, appeared in two Super Bowls and won one of those big games since the start of the 2021 season. 

Nevertheless, some associated with the Eagles are warning the club of what could be to come now that Harbaugh is clearly running the show for the Giants. 

Will Eagles do Giants favors early into John Harbaugh's tenure? 

"The Eagles are their own worst enemy most of the time," former Philadelphia assistant coach Ted Daisher recently said while discussing the Giants' hiring of Harbaugh, as Darryl Slater and Bob Brookover of NJ Advance Media for NJ.com shared for a lengthy piece published on Friday. "There will be some controversy or some type of issue. There always is. The Eagles will help you, give you some advantages."

History suggests Daisher is correct. The Eagles' latest run of success has also featured reports about the sometimes shaky relationship between head coach Nick Sirianni and quarterback Jalen Hurts. Philadelphia and wide receiver A.J. Brown seemingly can't wait to break up with each other, and a recent story claimed that Hurts "has been the source of much internal frustration" within the Eagles. 

Of course, that's not to say the Giants will be without drama. Harbaugh is reporting directly to team co-owner John Mara instead of to general manager Joe Schoen, and it appears that Schoen's days with the organization are numbered. 

Giants expected to win "pretty quickly" under John Harbaugh

That said, former Eagles coordinator and senior offensive assistant Marty Mornhinweg believes Harbaugh will have the Giants making things difficult for Philadelphia as early as during the 2026 season. 

"[The Giants] will win — and pretty quickly, too. All that losing they’ve done since they won their last Super Bowl, that will flip. He’ll flip the mentality," Mornhinweg explained. 

The Giants have notched just one playoff victory since they won Super Bowl XLVI in February 2012. With Harbaugh leading the charge, Big Blue will look to follow in the footsteps of a New England Patriots side that qualified for this year's AFC Championship under first-year head coach Mike Vrabel.
