You really can’t see the wood for the trees on this subject.
You keep repeating the phrase ‘world stars’ but cannot appreciate they are only ‘world stars’ because of the coaching and guidance and experience they’ve received since becoming professional sportsmen - on top of their raw, god-given talent.
Don’t you think there are people out there who would’ve made it to international cricket given the right environment?
Matthew Syed wrote a book about the talent over practice argument and it is very compelling.

I’m not suggesting practice alone can turn you into a world class player, but I do strongly believe that there are thousands of talented people out there who didn’t get the chance at the right time and therefore never realised their potential.
They’re out there doing menial jobs and living a normal life, but you don’t know about them because they never got the chance. They were never in the right place at the right time.
With Beefy and Flintoff you’ve used a pretty poor pair of examples, Botham was a professional footballer, I could easily have seen a scenario where he didn’t get a chance at cricket so made his living entirely from football.
Didn’t Flintoff also have trials at a pro-club?
There have been countless cases in local cricket in recent years too that suggest that the individual simply needed to be given a chance that never materialised. Not more telling IMO than the case of Karl Turner and how unfortunate he was with Durham and then Notts.
That only strengthens my point IMO regarding the small window of time between him being spotted and the family moving back to NZ.
