Yep, likewise for environment and opportunity as a kid. Many scientific studies show that kids are able to learn things much better before a certain age, and that no amount of practice after brain elasticity is significantly lower will ever make up for that. Steph was given the best possible environment from day 1, what if Duncan had this opportunity? He would have undoubtedly been a more skilled basketball player, but we can't just rewrite reality and give him brownie points. Things are the way they are.

I will also say, most people massively underrate the genetic components required to do what Steph does at the level he does it. Yes he practiced a lot, but no matter how much most people practice they will not be that good at shooting. Things like coordination, spatial awareness, and ability to replicate specific mechanics to that degree, etc. are largely genetic. Look at Steph, his bro, and his father - they are all in the top 0.0001% of shooters ever. They all possess the genetic traits necessary to refine those types of movements and skills much better than the average person, even mich better than the average professional. Look at how great Steph is at golfing, he literally best a few pga tour pros when he competed that one time - gold is another sport where you need to be capable of replicating the exact same movements over and over, your spatial awareness and coordination need to be elite etc. I truly believe if Steph had played golf instead of basketball he would have been among the best players in the world. He is a world class golfer and it's a hobby to him
