.the game has changed over the decades....recruiters pick them off early and put them through a process...there's still players from the hood...but those days of a recruit getting word of mouth of someone on the playground is long dead.
if you check the resume of a lot of NBA players..a lot of them came out of Catholic Schools because those schools are private and can recruit playrs with scholarships
On rare occasion you get a Tony Romo or Joel Embiid type who didn't start playing until HS...but the rest of them dudes start in youth programs
I'll never forget...when I use to run track and Kevin Jones (RB Lions/VTech) was 16 at the time running for Cardinal O'Hara HS....he was built like a pro and had two personal trainers/coaches watching his every move... before he was even known to anyone...we all looked at him like

and asked ourselves "who tf is that" like a scene out of coming to america 3 or some shyt.....they clearly knew what they were doing because he became the #1 Top NCAA football recruit in the nation in his senior year after mike vick left.., and went 1st round in the NFL
