Biggest issue facing NFL is demographics

and older fans dying and fewer die hard fans coming up. If younger folks play and like the game they will be fine. If, via, say immigration the tastes and interests of the next few generations are different from those of the WWII, Silent, Baby Boom, Gen X, Millennials then they will have issues.

Football isn't going anywhere, but it could flatten out in terms of growth and sometimes businesses get squeezed in that situation.
