Brenkus was also the founder of Brinx.TV and co-founder of the production company Base Productions. Widely recognised for bringing scientific insight into the world of sports, Sport Science used technology to break down athletic performance and debunk sports myths. The show first aired on FOX Sports in 2007 before moving to ESPN, where it went on to win six Emmys.
In 2023, Brenkus publicly spoke about his mental health struggles in a candid conversation with his ESPN colleague and former NFL player Marcellus Wiley. Recounting a particularly dark period after he had sold his company and was living in Park City, Utah, Brenkus described experiencing severe depression and suicidal thoughts.
"I was flat-out suicidal," he revealed, adding that his dog, Zeppelin, ultimately saved his life by interrupting his suicide attempt. Following that experience, Brenkus sought professional help and eventually found support through a psychiatrist in Virginia. He said at the time that he had not experienced depression since then.
Wiley reposted the announcement of Brenkus' death with a brief tribute, writing "RIP" alongside prayer and heart emojis.
Remembered as "an innovator, an entertainer and an educator," Brenkus leaves behind a legacy that redefined how fans understand sports through the lens of science.
