Well i have these three on my list:
1) Wu
2) Joshua Filler
3) Vilmos Foldes
There are MANY super-talented players but these three have shown their insane talent at very young age. Of course probably the most talented player of our time is Wu who became double world champion by the age of 16,you just cant beat that
Joshua was killing his opponents at Eurotour at the age of 11 and won China Open at the age of 19, Vilmos began to tour european tournaments at the age of 12 i believe,became world junior champion at the age of 18 and bronze medalist at world championships in mens division at the age of 22. Another notables would be Albin Ouschan, Chang Jun Lin, Yang Shin Sun...too many to name them
But it is Wu who proved your point, he didnt play pool for several years because of life circumstances (military service, leukemia, international ban by chinese taipei federation..yet he was able to return to the very top of the international pool circuit.So yeah, it is Wu for me.
