That was interesting. At my perspective from my age, it's no surprise that proper training from an early age by their father along with hard work and making it a priority (work in the basement at enhancing your skills rather than playing Nintendo) led to the sons become as good as they are. Genetics and innate ability can only take one so far. When I was a kid, I used to believe a myth that people had God-Given talent. Bull-crap. lol
I disagree that the innate ability/genetics play a lesser role than hard work. I could have worked twice as hard as the Gronks and still would have maxed out at high school level sports. My thought is that great innate ability (w/o hard work) will take you only so far just as hard work (w/o innate ability) will only take you so far.
EVERY professional athlete started with a base of skill potential that I could never attain regardless of work ethic.
Yeah takes both innate ability/genetics
and hard work. It also takes attitude / personality to
believe that your hard work is making a difference and improving your skills. Maybe the person who has more innate ability and genetics thinks
"this is easy so I will work harder". I'm sure there are more significant factors involved.
That's also a good point about the 'vitamins'. lol. I'd be shocked if there's a decent portion of professional athletes who
don't take any form of 'vitamins' whatsoever.
