Watch: Will Smith Fights the NFL as Dr. Bennet Omalu in the Trailer for ‘Concussion’

As someone who has suffered only one concussion, which has been more than moderately traumatic, I can barely imagine what these football players have and continue to experience(d).

Thanks to Will Smith and the filmmakers of “Concussion,” coming out this Dec., 2015, for bringing concussion syndrome to more people’s attention.
