CNN American Morning’s John Roberts talks to Sport Illustrated reporter David Epstein about his year-long look at one group of high school football players in Indiana and the brain injuries they sustained, not by concussive hits, but hard tackles. Dr. Steven Flanagan from NYU Langone Medical Center’s Dept. of Rehabilitation Medicine, joined the discussion, on whether high school football players are being unwittingly suffering long term damage from not just concussions, but frequent hits.
