Potentially yes. But I would not agree in all cases. Does the teenager enjoy the activity? That could be reason enough for him to pursue it. And there's shades of grey here we're not addressing... OK so he doesn't have Jordan's innate talent, but does that necessarily mean he has no chance at all of pursuing a pro Basketball career? Of course not. There are many still valid and useful skill levels between the two extremes of "not fit for the NBA" and "Michael Jordan".
