The reason blacks dominate sports that are highly paid is because they have nothing to lose. A white man is expected to have a family, a job, civic responsibility, etc. while blacks can dedicate their 100% waking life to "making it" in Jew-run sportsball mafias.
The reason that "white sports" don't make it to the big time other than perhaps UFC and perhaps hockey is precisely because those sports are not promoted in nignog circles as a way to become rich.
Look for nigs to become rappers, athletes, or drug dealers. Their motivation is entirely pecuniary. The white man can't actually operate like that mode without going homeless and broke, which is the nig's default state, not his.
