I mean, the NFL right now is nothing like the NFL I've watched growing up as a kid. NFL was marketed less about skill and more about size

and power back in the day. So I know a lot of people will disagree here about the NFL being peak. And hell, if you remove NFL no one else really plays traditional manner football on pro level. The pro football/NFL phenomena is crazy because for hockey and baseball and basketball there are other leagues that are inferior, but still competitive and pro, for football theres basically nothing even comparable.
The globalism aspect of basketball is the reason why you're even able to compare euro rules to NBA.
I get what you're trying to say tho
