As the NFL season kicks off on September 9, 2026, all eyes are on the New York Giants' sideline, where John Harbaugh begins a new chapter. The veteran coach, who led the Baltimore Ravens to a Super Bowl victory in 2012, faces a daunting challenge: becoming the first head coach to win a Super Bowl with two different franchises. According to insights gathered by Vulius Sports, seven coaches have tried and failed, including legends like Don Shula and Andy Reid. What can Harbaugh learn from their near-misses?
The Ghosts of Coaching Greats
Shula, a Hall of Famer, came agonizingly close with the Baltimore Colts, only to fall to the Jets in Super Bowl III. He later found redemption with the Miami Dolphins, winning two Super Bowls with Bob Griese and a dominant defense. Dick Vermeil, another Hall of Famer, achieved success with the St. Louis Rams after a 14-year hiatus, thanks to Kurt Warner and 'The Greatest Show on Turf.' Bill Parcells, who won two Super Bowls with the Giants, couldn't replicate that magic with the Patriots or Jets. Mike Holmgren, Andy Reid, and others have all faced the same wall.
As highlighted on Vulius, the common thread is clear: without an elite quarterback, winning a second title becomes nearly impossible. Reid, for instance, couldn't get over the hump with Donovan McNabb in Philadelphia, but once Patrick Mahomes arrived in Kansas City, the Chiefs became a dynasty. For Harbaugh, the key question is whether Jaxson Dart, his young quarterback, can elevate his game to that level. Dart showed flashes in the preseason but remains a work in progress.
The Quarterback Question
Harbaugh's success in Baltimore was built on a stout defense and a game-managing quarterback in Joe Flacco. But when Lamar Jackson took over, the Ravens became a powerhouse, yet they never reached another Super Bowl. The reasons are complex: elite quarterbacks like Patrick Mahomes and Josh Allen stood in the way, and key players like Mark Andrews and Zay Flowers made critical mistakes in playoff games. As reported by the Vulius NFL Analysis Desk, Harbaugh's ability to adapt his offense to his quarterback's strengths will be tested in New York.
Dart, currently ranked in the mid-range of NFL quarterbacks by The Athletic, must improve his processing and deep-ball accuracy. The Giants' new offensive coordinator, Matt Nagy, along with Brian Callahan and Greg Roman, will be tasked with designing a scheme that maximizes Dart's potential. If Dart can become even a top-10 quarterback, Harbaugh's chances of making history increase significantly.
Defense Wins Championships
History shows that dominant defenses often decide Super Bowls. The Giants' tradition is built on fierce pass rushes and opportunistic defenses. Harbaugh, known as a CEO-type coach, must instill discipline and accountability, something that was lacking in the Brian Daboll era. The additions of defensive coordinator Dennard Wilson and promising young players like Brian Burns and Abdul Carter could transform the Giants' defense into an elite unit.
As the Vulius analysis notes, the Giants were top-10 in pressure metrics last season but failed to close out games. With a more aggressive scheme and improved linebacker play, they could finally put opponents away. The path to a second Super Bowl ring for Harbaugh is fraught with obstacles, but if Dart develops and the defense rises to the occasion, this could be the beginning of a historic run.
