Sometimes my arm hurts just replicating some of their pitches in slow motion. I have a long held belief that the most talented pitchers of all time never made it to pro ball for exactly this reason. A less commonly acknowledged attribute is being enough of a genetic freak that one's arm doesn't slag out.

Or could it be that part of talent as sportsman is to have genes/body that is at extreme of the curve. There is talent to be able to throw one ball, but entirely an other talent to be able to keep throwing nearly as good balls. And later has much more value in professional setting.

That's basically my point. The ability to persist is undersold when people talk about required talent. The most physically gifted quarterback on the planet is worth nothing if he gets ripped in two the first time he's sacked.

That is already true for most pro sports, the people that make it to the top are already freaks of nature.
