Fans reacted with shock and sorrow across social media platforms, with many acknowledging his impact and addressing the ongoing importance of mental health awareness.

Tributes from the sports community quickly followed. Robert Griffin III, American football quarterback, posted on X, “Prayers up for John Brenkus and his family. The man who gave us the Emmy Winning Sports Science lost his battle with depression…”

Marcellus Wiley, American football defensive end, wrote, “RIP @johnbrenkus_.” Mardy Fish, American former tennis player, added, “Was lucky enough to do a Sport Science with John a while back. A great man. Please seek help if you are struggling. YOU ARE NEVER ALONE! RIP John.”

A previously recorded YouTube video from January 2023 resurfaced in the wake of Brenkus’ passing. In the emotional conversation with Wiley, he opened up about his mental health struggles.

“So the time in my life where I was counted out, where I counted myself out, I was living in Park City, Utah, and I fell into a very deep depression,” he said.

At the time, Brenkus had recently sold his company and “Sport Science” to ESPN. He believed he had reached a pinnacle in life, but the reality of isolation, physical setbacks, and a lack of routine caused his mental health to decline.

“And you know, the isolation that you feel living in a mountain town — the cold weather, injuries, things not going right — I spiraled into a deep, deep depression, and I was flat-out suicidal,” recounted Brenkus.

Brenkus reflected that he had reached a critical point, but his dog, Zeppelin, intervened at the right moment.

“I was ready to do it, and my dog Zeppelin came to my rescue — literally pulled on my pants, on my jeans, and literally was going crazy, wouldn’t leave me alone,” he recalled. “And I, like in my suicidal funk, was like, what am I doing?”

That moment became a turning point. “I literally picked up my phone, called my mom. I said, there’s something wrong with me. I am, like, mentally lost,” he noted.

Brenkus described a difficult road to healing. “I then went through a battle — I mean, I’m telling you, a battle — to get out of it,” he revealed. “I went to six different psychologists and psychiatrists. Finally found my answer. Finally found the way.”

He credited Dr. Cindy, a professional in Virginia, for helping him recover. “We found a solution, and I have never been depressed a day in my life from that moment forward,” he shared.

“And I am so grateful for the angel, Dr. Cindy, who came down and really was able to demonstrate to me that depression is not about being sad — it’s about the way that we are constructed as humans having thought loops,” discussed Brenkus.

Brenkus emphasized that these “thought loops” could trap people in a mental cycle, even when they seem fine externally. “And that’s why you see people who seem like they’re perfectly fine, but inside their head they’re just looping and looping and looping and they try to quiet those voices,” he explained.

“Unfortunately, look — mental health, suicide — it’s a real thing. And I counted myself out. And I consider it my greatest blessing and greatest victory that I went to and had to march through the valley of darkness to get where I am today,” he remarked.

In the same interview, Brenkus highlighted the need to end stigma around mental health. “The darkness is very real, and it’s inside all of us. It’s hardwired — that and the looping and looping and looping.”

He mentioned, “The conversation that we’re having as a society about mental health — for whatever reason, there’s like this stigma to it. That, ‘Oh man, you need help, you are not healthy mentally.’ If you say, ‘My God, I suffer from mental health issues,’ people can look at you like, ‘Oh my God… that’s what’s wrong with you.'”

“Therefore, something like depression — which is just a thought loop you can’t get out of your head — you don’t share it with anybody. You feel embarrassed about it,” stated Brenkus.

He recounted a moment of mental crisis. “It really [was] all about that moment of darkness and really reaching the ultimate darkness where — my God — I want to kill myself. For whatever reason, it makes sense when it’s that dark.”

Despite the despair, he offered hope. “There are hotlines. There are friends. There are family. There are other people. Talk about it. You have to tell people, ‘I’m not thinking right, and I know I’m not thinking right, and I know I can’t find my way out all by myself.'”
