It may seem to the casual observer that the National Football League is impervious to an uncertain future.
After all, it has become a driving force in the American economy; a sport which has eclipsed all others, fueling billions of dollars in gambling and spawning fantasy leagues that fascinate tens of millions of Americans.
The league has $6 billion worth of TV contracts, gleaming new stadiums built with taxpayer dollars and a sweetheart deal with the federal government that allows it to skip paying any corporate income taxes while paying its commissioner $30 million a year.
The NFL rules.
But the throne it sits on relies on a player pipeline that begins in the high schools and carries forward with "student-athletes" in colleges and universities that function as an NFL minor league.
And that pipeline is starting to get tested as the danger and prevalence of concussions in the sport becomes more evident.
So despite its obvious strength, the future of the NFL is more tenuous that it appears, and in the hands of mothers in Florida, Texas and other incubators of would-be future talent.
In the past, the NFL has acted much like the cigarette companies, by introducing junk science to downplay the health risks associated with its product. To do this, the league formed a Mild Traumatic Brain Injury Committee which authored scientific papers that made football concussions sound benign.
