In my area, I see it all the time, the tendency to discount an athlete because the athlete seems 'untalented' but it's really because the instruction wasn't adapted in such a way that the athlete could really 'see' it and 'do' it. One coach told me that his softball player was 'too scared' to slide into base so he was ready to give up on her and kick her off the team. When he had tried to teach her to slide, he kept saying the same things over and over and didn't adapt what he was saying so she comprehended. I had to teach him that if you've said it a few times, and the person still isn't doing it right, then try saying it a different way, and a different way, and a different way, and demonstrate, and get her to watch others, etc, and all the many different ways you can possibly teach someone a skill instead of assuming 'they just suck at it'. Saving the world one athlete at a time.
