The article says grit and mental toughness are necessary and sufficient for elite performance, and that such attributes can be learned, ergo anyone can be an elite performer. Adding luck as an attribute pours water on that theory: Mental toughness isn't enough, there's ceiling on how far one can go with grit alone.

Anyone can be an elite performer with enough training and effort. Not everyone can be top 10 though. At some point genetics plays a role. But to be _elite_ does not imply being top 10. If you are ranked the 500th professional tennis player you are far from being a Nadal or a Federer, but that’s still an incredible level of performance. There’s only 500 other humans on the planet that can match up to you.

This is a tautology. Of course there's a ceiling of how one can go with [X] alone, (in fact, given any [X]). It doesn't pour water on the theory at all, it's just an uninteresting and fatalistic point of view.
