"I know it is difficult for a 12.8 second 100m guy like Sprintgeezer to understand that level of talent, but it does exist."
No, I have seen it. In my own family there is a guy who does nothing but fish and watch TV. When he was young and I was practicing some shot, he picked one up and threw very close to the (still-standing) US HS record on his third and last throw. I am not kidding. Record for 16-lb is Carter's 20.65, from 1979.
I absolutely could not encourage him to pick it up again, no matter what I did.
If I had even half that guy's talent I would have been sub-10.
I understand levels of talent. I also know that the chance of any McTear running 9.80 or better, FAT, if they were running cleanly today, would be vanishingly low, given what we know about the performances of all the intervening athletes around the world.
I also know that there is a lot of myth and hyperbole. I also know that PED's work, and that guys take them.
Yes there are outliers. In the 100m an outlier would be going 9.8's cleanly, maybe 9.8-low, while everyone else was stacked between 9.90 and 10.10. 9.95 and 10.10, actually. Not 9.5
I do admit that we might see a whole new era in sprinting in particular, with a whole crop of 9.7/9.6 guys, maybe in as little as 5-10 years.
