“There’s no correcting it. There’s no helmet that’s going to correct it. There’s no teaching that’s going to correct it. It just comes down to it’s a physically violent game. Football players are in a car wreck every week.”

The disturbing issue of concussions was highlighted in Will Smith‘s film “Concussion,” which tells the real-life story of Dr. Bennet Omalu’s discovery of the link between brain injury, chronic traumatic encephalopathy (CTE) and professional football players, and the NFL’s denial of the connection.

On Dec. 30, just days after the movie was released, New York Jets offensive lineman D’Brickashaw Ferguson wrote a first-person essay for Sports Illustrated saying he felt betrayed by the NFL since watching the film.

“Since seeing ‘Concussion,’ I can’t avoid wondering if I am in danger of experiencing some degree of brain injury when I am done playing,” the lineman wrote. “I fear the unavoidable truth is that playing football has placed me in harm’s way, and I am not yet sure of the full extent of what it might cost me.”

In November, pathological tests proved that New York Giants great Frank Gifford — who died earlier in 2015 at age 84 — had suffered from the progressive degenerative brain disease CTE.

The Gifford family, including Frank’s wife, “Today” show host Kathie Lee Gifford, had donated his brain to science and disclosed his condition “to honor Frank’s legacy of promoting player safety dating back to his involvement in the formation of the NFL Players Association in the 1950s,” they said in a statement.
