I mean again, even within a single sport, there are role differences, but the degree of fitness that you have to have to build 130kg muscle mass that JJ Watt has, and to run the 38.5 that Mbappe does... is just not the same level of fitness.

On the reverse, Mbappe has less strenght, and JJ Watt moves like a tank with 27km/h speed. If you compare them to elite strenght sports, they're both weak. If you compare them to sprinters, Mbappe is an amateur sprinter, and JJ Watt is disabled.

Sportsmen specialize in what they do, but NFL simply doesn't require versatility so they are good in fewer categories, and not very good in any. Soccer players are good in multiple categories, and by the virtue of being the more popular and competitive sport and having insanely bigger selection, occassionally very good in one or two (e.g. Bale, Mbappe, and other freaks of nature who are essentially sprinters).

Also, soccer player does not run 1/20th of marathoner runs. Elite wingers run just under _a third of marathon_ each game, of which 3km can be sprint.
