Probably won't be here in 50 yrs, not sure if I want to be here in 50 yrs.
I think the NFL is in for some serious change and 50 yrs is about right to see this change.
This info is out there I know but just using the common sense method...the 1st effect I think we might see is reduction in the gate.
The NFL fan base that buys season tickets is probably closer to 35-60. The next generation of people to hit that age group (20 somethings) are not huge NFL fans. I can see a drop off at the gate as the current fan base start to give up their tickets.
At the grass roots level...There will always be players, but the numbers will be impacted by the concussion risk.
NFL on TV will carry on for quite awhile, but soccer does have a chance to overtake the NFL...as Americans become more and more interested in the game and the foreign population continues to grow...in 50 yrs I can see it happening.
