Yeah, Olli Jokinen once explained this.
He was coached by the Great One, moving up the ice in practice, head on a swivel, looking to pass to a teammate.
Afterwards Gretzky asked him, why didn‘t pass to the 4th guy who just stepped on the ice and was out of sight, exactly behind him crossing the blue line.
“Coach, I didn’t see him, even if I tried.”
Gretzky looked puzzled…”Yeah, but didn’t you KNOW where he was?”
It was OJ’s turn to look puzzled. But at least he realised that Gretzky has an otherworldly vision and IQ.
You just can’t teach it. And if you are not able to understand the limitations of your players, you become a shitty coach.
