NFL concussions are a serious problem, so Sony Pictures decided to make a serious film about the recent crisis. It's titled Concussion, in case anyone is unclear on football's most serious issue. But we don't really need to watch a fictionalized version of Dr. Bennet Omalu's story, even if it does star Will Smith. The Nigerian-born nueropathlogist who first discovered chronic traumatic encephalopathy during autopsies of NFL players, and who fought the league to get the truth out despite their attempts to "squash" him and his colleagues, talked at length about his research in League of Denial, a PBS Frontline investigation of "what the NFL knew, and when it knew it." You can watch it right here, or on the Apple TV app. PBS also has a dedicated page following the concussion crisis, with updated stats and stories, interviews with effected players, and a look at advancements in technology.
Or just wait to see the movie when it opens Christmas Day, after nearly 90 percent of this NFL season's games will have been played and more than 100 athletes, on average, will have already suffered concussions. It still looks pretty good.
