So many interesting thoughts and comments from the community.
I agree with many of the observations and the insights.
I think I should clarify that my reason for posting is not to predict the demise of the NFL. I think the NFL will find ways to drive consumption of their product for years to come. There's too much money behind this -- it employs too many people and generates too much revenue to simply go away without a fight. And the stadiums... what to do with those stadiums?
But Someone mentioned tobacco as a analogous industry... That's probably fair in the sense that football is as synonymous with American culture today as smoking was to American culture in the 40s and 50s. The NFL will resist and it may take time for the demand to wane.. But the NFL will decline primarily because of the quality of the product -- the talent will be depleted.
And that leads to the main reason I posted this: because I believe the medical evidence will lead to 1) a reduction of kids who want to play the game, and 2) a chilling effect on the funding sources to public institutions such as public high schools and state universities. These constitute the pipeline for talent to the NFL.
State funds -- taxpayer's money -- cannot support actives that are known to harm students. The threat of lawsuits against the institutions could move up the chain to the states that are funding / supporting the sport. To continue to fund football would be akin to using state funds to put cigarette vending machines in schools and campuses.
Private schools and academies may continue to support football programs, and perhaps they will surge as a source of talent to professional football as the traditional sources dwindle. But that won't be enough to keep the sport at it's current level of prominence /dominance.
As Football declines, a void will be created. Basketball is already poised take it's place at every level. And when basketball becomes #1 in popularity (in College Athletics), it will also replace football as the #1 source for fund-raising a the collegiate level from alumni and donors.
Take THAT conference realignment! KU looks pretty good in this context.
@mayjay you are right that Soccer is the #1 sport worldwide. My point is that basketball has more global popularity than football and is poised to become increasingly popular around the world (see olympic sport, the number of foreign players in College and NBA... etc.)
If I was an investor, I would sell football and buy basketball.
