The sports thriller is based on the true story of Dr. Bennet Omalu, a Nigerian American forensic pathologist who fought to prove that repeated blows to the head while playing football resulted in numerous athletes developing the brain disease chronic traumatic encephalopathy, or CTE.
Before the movie was released to the public, Sports Illustrated’s Monday Morning Quarterback screened it for 70 former NFL players and their families.
“I watch this movie and I know we were paid to hurt people,” former linebacker Keith McCants told Sports Illustrated at the time. “We were paid to give concussions. If we knew that we were killing people, I would have never put on the jersey.”
CTE is triggered by concussions and other hard hits to the head. The brain disease is associated with memory loss, confusion, impaired judgment, impulse control problems, aggression, depression, and progressive dementia, according to Boston University research
Last year, researchers with the Department of Veterans Affairs and Boston University found that 87 of 91 deceased former NFL players suffered from CTE, “Frontline” reported. Additionally, 131 of 165 individuals who played football at any level ? professionally, semi-professionally, in college or in high school ? tested positive.
In May, the NFL for the first time publicly acknowledged a link between football and CTE. Meanwhile, concussions remain a serious threat for players.
In 2015, the NFL counted 271 diagnosed concussions in practices, preseason and regular season, compared with 206 in 2014, and 229 in 2013, ESPN reported.
The league has said it is “deeply committed to continuing to accelerate scientific research and advancements in this critical area, and we stand ready to support additional independent research to that end.”
In April, a federal appeals court upheld an approximately $1 billion concussion settlement between the NFL and thousands of former players.
