Mike Florio Discusses the Possibility of NFL Teams Having NIL Funding

The key example is Kansas City. One of the smallest markets in the NFL. And also quite isolated, they don't border other significant markets, as New Orleans does with Baton Rouge or Buffalo does with Toronto.

But Mahomes, Kelce and Reid are featured in national adverising campaigns and almost certainly getting paid $$$ for that. If you're good and win in the NFL, you don't have to be in LA/NYC to get paid.
The one difference between the NFL and the NBA as I traveled across the country for work is that NFL teams are regional while NBA teams mostly are just centered in the actual market they’re in.
The Saints market isn’t just NOLA. It’s Mississippi, and parts of Alabama and Pensacola.

It also helps that every NFL TV contract is a national contract. No games are stuck in the purgatory that is a regional sports network.
