Well, Swervin, I was expecting this reply from someone.
First of all, you misread what I wrote. I didn't say the NFL was shutting down, in fact, I said the opposite, "The sport will continue to exist professionally."
And is LeBron James an over-bearing parent? Because LeBron doesn't want his kids playing football, a sport that he says is his first love, more than basketball. And many ex-players don't want their kids playing either. Its not over-bearing to have your kid play basketball, soccer, lacrosse, or several other physical sports, all of which come with injuries, instead of football or boxing, which both cause brain damage. Its simply a smart decision, that is, if you care about the health of your son's brain.
The sport of football is undoubtedly more popular than any other in America. I wasn't being foolish, I know that. And I think its popularity as a SPECTATOR sport will continue for many years. But the pipeline of players will slow and narrow, and that's not a projection, its an observable fact. Youth football numbers are suddenly WAY down in many areas.
In areas, such as small Texas towns, football is embedded into the local culture and will continue there longer than in other places, but even that is not a guarantee. Baseball was an important part of black culture in America for a long time, and the cultural importance of Jackie Robinson only enhanced it, and by the early 70s, over 25% of all MLB players were black (U.S. born). But within about 20 years, the percentage fell to under 5%, as other sports, football and basketball, simply replaced baseball. I know a few older black guys who still can't believe that the change happened. The point is, a sports popularity -- as a sport that people play, not just watch -- can change quickly. The current popularity of football on TV doesn't guarantee anything in terms of what kids will play.
