The NFL may be the last bastion of football in 50 years, because I can imagine the slow death of the sport creeping up from the youth level, if we keep finding out about the long-term effects of brain damage caused by the game, it's hard to imagine many parents will allow their children to play. Maybe high school and college football go away. And maybe football becomes more like MMA -- a sport that has relatively few participants, but enough to entertain the masses, with athletes willing to take obvious health risks to achieve money and fame.
