This week, former Steelers running back Merril Hoge and Boston University neuropathologist Peter Cummings released a book challenging the link between football and CTE — the brain disease found posthumously in a couple hundred former NFL players, including suicide victims Junior Seau and Dave Duerson. In promoting the new book, Hoge and Cummings penned an Op-Ed for Yahoo Sports that questioned CTE research and the media “hysteria” surrounding it.
