I thought my point was clear...maybe it wasn't.
Football has a 77% white audience. 15% black and only 8% hispanic.

It has an audience that is overwhelmingly a. white, and b. American. White Americans are dwindling in number. Leagues of sports with international audiences like soccer and basketball are better equipped to deal with that.
I don't think immigrants from Asia, Latin American, and Africa that supplant white people a bit will just fill their shoes as consumers of football. There will be some drop off. Hispanics are the most rapidly growing group and they only make up 8% of football viewers now. It's not about dominant culture trumping anything because dominant culture is fluid by generation.
Why are you assuming these ppl are all fresh off the boat? There's millions of them HERE RIGHT NOW and have been for years, and 25-30 years from now maybe whites will dwindle in number, but by that point, the other groups will make up the difference in NFL fanship. And let's say for example there's 300 million white ppl in the USA, the majority of them are likely not NFL fans as it is
Do you realize how many millions of Mexicans in Dallas ALONE who are huge Cowboy fans. They go to games, buy jerseys, everything. They spend TONS of money.
Football is american culture, and other races have & are ASSIMILATING into American culture.
The same way white people, hispanics, asians have assimilated into hip-hop to keep it alive.
