If anyone would deny that the NFL is crooked, then would advise they watch...the show I saw on frontline last night. lol. Concussion has been their bane for a while now. It looks as if repeated hits which do not concuss are extremely dangerous in accumulation. Like boxers, where it has been a confirmed issue. The NFL has used "team" doctors to support their (three point- lol) stance. They deny that repeated hits to the head cause health issues later in life. ..Slices have shown that 19 of 20 ex nfl'ers brains obtained had brain injuries. Other contact sports- wrestling/hockey have also shown similar behaviors in men displaying uncharacteristic displays of violence/addiction. NFL commissioner Goodell is head of a multi bilion dollar industry. His denial of concussion evidence is disconcerting. Not to mention recent issues of player criminal violence-(caused by concussed players?) and how he handled all those multiple cases. Could this be the beginning of the end for NFL, eventually hockey?
