IF they do that, there will be some league that pops up that provides the public with tackling football in some form.
That won't happen though, because the popularity (and therefor $$$) is just to high to change the current model.
What WILL change, and should, is that the NFL should go to guaranteed contracts and lifetime care for anyone that plays a certain amount of years. These guys put their future on the line more so than any of the other major sports and should be compensated for it. No talent, 12th man NBA players make more than some of these guys do WITHOUT the fear of long term brain damage. And I'd say about 60% of the NFL players can be cut tomorrow without any compensation at all.
It's a violent game.....but taking that violence out would change everything.
Maybe this pussified generation of young kids that is coming up will change it someday.......but not any time soon. Hopefully the Lions can win a Super Bowl before that happens.
