Greg Harden, a transformative figure in the athletic realm, left behind a legacy far beyond the field, court, or pool as he breathed his last at 75 years of age last Thursday. Known as the man behind the curtain, he became a driving force in the lives of some of the greatest athletes in modern sports history, including NFL legend Tom Brady, and Jim Harbaugh, and led the Michigan Athletics to the zenith. Besides the NFL powerhouses, Harden also shaped the success story of U.S. swimming legend Michael Phelps.

Michael Phelps, the Baltimore Bullet with 23 Olympic golds to his name, was just one of the many stars who sought Harden’s guidance. Harden’s influence reached deep into the hearts and minds of those he mentored, helping shape their personal journeys, not just their athletic careers. On the one hand, Greg was referred to as the ‘secret weapon’, while on the other hand, Phelps also stated the fact that Harden’s transformative power was a ‘blessing’ to him. 

After hearing the news of Harden’s passing, Phelps took to Instagram to share a heartfelt tribute. Posting a picture with Harden on the Instagram story, Phelps wrote, “My Guy G. I’m so blessed for our time 🙏🏻 R.I.P.” 

Joining Phelps in a heartfelt tribute, Tom Brady also took to X and wrote, “I’m so sad to hear the news of Greg’s passing. I’m heartbroken as he was a dear friend and mentor. There are so many beautiful qualities Greg had that endeared him to so many people over his years at Michigan. He meant the world to me and I could never have had the success I had without the time, energy, love and support he had given me. He will be truly missed ❤️” Harden was admitted to the hospital a few days ago and had to undergo critical surgery last Monday. However, unfortunately, his body succumbed to the after-effects of the surgery and breathed his last at 75. 

Michael Phelps’ lifelong mentor penned a bestseller during retirement days at the age of 74

Besides shaping the career and adding colors to the lives of the athletic figures who attained legendary status in their sports, Greg Harden also authored a book that debuted at #1 on all of Amazon. His book titled, Stay Sane in an Insane World: How to Control the Controllables and Thrive went on to become a bestseller. But that’s not all! Harden trained the greatest NFL quarterback, Tom Brady was guided and mentored by Harden.

Acknowledging the undeniable impact Greg had on Brady, which reflected on his career graph, Brady stated, “He (Greg Harden) meant the world to me and I could never have had the success I had without the time, energy, love and support he had given me”. Former NFL wide receiver Desmond Howard, who grabbed the Heisman trophy after being selected as the unanimous All-American, considered Greg his mentor, friend, and philosopher. While stating that he would miss him, Howard added, “Greg brought wisdom, joy and his calming nature to every encounter”. 

Hailing from Detroit, Harden earned a postgraduate degree from Michigan University and retired from his counseling career in 2020. However, he never embraced the quiet life of retirement. Instead, he continued to inspire and uplift young athletes in Michigan, spreading positivity and guidance.

Even at 74, his passion shone through with the publication of his book in 2023. Even after stepping back from his career, Harden’s unwavering dedication to coaching and mentoring truly showcased his worth as a life coach. May his soul rest in peace, and may the athletes he guided continue to carry his legacy forward, achieving great success. As his family rightly said, “In the future, they look forward to celebrating Greg’s life with many who were blessed to know him.”
