Professional sports leagues aren't the keys to wealth and power in this country. That's why there's a big fuss over college admissions and not about sports.
I'm failing to find a more colorful way to put this so here it is plainly:
One becomes an affirmative-action-privileged race precisely because there are systematic barriers to the keys to wealth and power. If sports were that, and there were systematic barriers to it, we would be having this same discussion about Asians. Being good at sports is overall irrelevant to wealth and power in this country.
