I had an LLM first pick five figure skaters, and in the follow up query tell me which had wild success before age 12, and only two of the five fit that category, but each started learning at 6 years old or earlier. The other three seem like child prodigies in retrospect to me.
Hakeem Olajuwon - didn't start basketball until 15 or 16.
Kurt Warner - undrafted, returned to NFL at 28.
Francis Ngannou - started MMA at 26.
