Former Heisman Trophy winner Herschel Walker, the SEC’s all-time leading rusher and one of the greatest running backs in college football history, opened up about overcoming anger issues and mental health problems during Thursday’s appearance on ‘Highly Questionable’ on ESPN, a talk show hosted by Bomani Jones and Dan Le Batard.

Promoting an upcoming MMA event, Walker went in-depth concerning his post-football struggles including a frightening revelation involving a game of Russian Roulette, before strengthening his spiritual relationship and searching for answers with his wife.

“At one point of my life, if anyone had ever crossed the line with me, there’s no a doubt in my mind I would’ve hurt them,” the three-time All-American at Georgia revealed during one segment.

“I would take a bullet, put it in a cylinder, spin it and tell you to pull it,” Walker later said. “I was so fired up that I could overcome anything.”
