Only reason this does happen more, though there is definitely a limit, is few people actually try.

Just one example, even I do have experience, still so far fromIRW USA FB it is not even funny.
Using F.ront P.age S.ports: F.ootB.all P.ro series (even though I have been a superstar PWFBL & bad HS player & a PWFBL & bad HS coach- in the best USA FB area in The World, M-Dade County, Fl., it only came to me through FPS: FBP series playing) I invented a complete (from regular plays to special teams) set of Offenses & Prevent Defensive plays. I know they would work IRW USA FB, because I have been a superstar PWFBL & bad HS player & a PWFBL & bad HS coach- in the best USA FB area in The World, M-Dade County, Fl., but because I am boycotting IRW sports, it will never be seen IRW USA FB.

So I could see some IRW teams, programs & franchises hiring only F.ront P.age S.ports: F.ootB.all P.ro series players, to become plays & plays adjustments creators, in the future. I know much of USA FB moves so slow to change that might take a while, but it will happen. The reason for only F.ront P.age S.ports: F.ootB.all P.ro series players is because F.ront P.age S.ports: F.ootB.all P.ro ‘98 still to this day has the very best plays, game plans, profiles creator-editor, & it is not even close.

That's true about everything. How many Mozarts are out there that never picked up an instrument? My son has a world-class, heartbreaking singing voice. In high school, he had the lead in every musical, and girls would literally cry when he sang, but he has absolutely no interest in pursuing it, even as a hobby.

How many great writers, great chefs, great runners, great artists, even great mathematicians, etc. who just weren't interested in the subject?

As a Former PWFBL-HS USA FB DE, TE Positional Coach & Degreed & certified in many areas Physical Education Facilitator, that required two-college level courses in Kinesiology & biology of sports, after switching from ESE…
I think there are some that are not in the particular sports that if they trained hard & for long enough
Or
If as already pointed-out in other posts, if already athletes in other sports competed in sports, that have crossover skills, then they could set new world records in test of those crossover skills,
But only some, I think most people are probably thinking too many people could do it.

I compare to contestants on Jeopardy, there are former long t8me champions, that had everyone wondering what made them so smart, bar tenders & Etc., but again, not as many as most of us would believe.
