Football is headed for an uncertain future and it has absolutely nothing to do with concussions. People don't care about other people being in pain as long as they are getting what they want. As far as the pipeline goes, as long as there are poor people and football players get millions you will have players. What's gonna do football in is the same thing that did boxing in...becoming too expensive/more trouble than it's worth/distancing themselves from the fans. The NFL seems as if they are actively trying to find that point where fans say "Enough!".
