NS.. ex-NFL players sue league... It's starting to make sense now

There was sports related brain damage information available many years ago, though more specific studies have been done and much more is known now. In the early eighties, I recall extensive media discussion about the combination punch causing brain damage in boxing. The explanation at the time was that the brain is not secured to the skull. When the head is rapidly turning in one direction and gets popped back in the opposite rotation, the brain twists within the skull causing lesions and tears in the soft connective tissues between them. These wounds leave scar tissue that diminishes the brain's capabilities (cause brain damage). Look at Mohamed Ali. Playing in the NFL is analogous to boxing in many respects. The big "jacked up" hits we love to see cause similar damage. Everybody has known it but they were in denial to keep the status quo going until it became impossible to ignore any longer.
