I think your post is remarkably US sports league myopic.
I think the very best at most sports could have been great at other sports. If Mikaela had been a soccer player from day 1, I have a hard time believing she wouldn't have been awesome at it. And I have little doubt that Tiger could have crushed it at other sports. The NBA, maybe not because he's not tall enough, but he would have been a hell of a baseball player, I bet. So I think the idea that Aaron Donald would be better at golf than Tiger would be at some other sport is not only unprovable, but a silly assertion.
And yeah, true freaks of nature.
