Hell, that in the entire myths of human history there isn't a better swordsman that a martial artist who learned a single thing?
With half-gods, various super-humans and so on? This is my point. People who ACTUALLY used their skills and refined them in true fighting?
It's like chess, you don't improve your general ability by trying a single thing, because the real deal is different by alone training.
TL;DR Sasaki didn't actually do shit in his life, only learned one attack that in practice could not work as expected, because situation can be different.
In SN without his position he wouldn't be able to defend himself from someone like Cu, without bringing in Herc.
