alt Hacker NewsEven though chances of succeeding in any are small, a potential athlete has far more to gain by being successful at football/basketball/baseball than at soccer. It's nearly impossible for even a star athlete to succeed at more than one sport, (see also, Michael Jordan) so anyone who wants to be a famous athlete has no incentive to train for anything other than the top three sports.

I don’t think that fully aligns with my observations. The US outputs plenty of star athletes in minor sports. Swimming, boxing, gymnastics, etc. It’s not all incentives like the mythical economic rational actor, especially when we’re talking about choices adolescents are making.
I think there is a more self selection process happening for athletes and sports. People with natural athletic inclinations try lots of sports young, they will do well in the ones they are most suited for, and begin taking that seriously.

I don't think this means as much as you're putting weight into.
I think the fact that somebody like MJ or Tim Tebow could even get a try-out in a different profession sports really speaks to top level talent being fungible. Like just imagine somebody practices being a Doctor for 20+ years and then gets an interview to be a World Cup Referee. Sure, they might not succeed at the other sport but the fact they can still do it is I think proof of sports fungibility.
