You said that you can't teach someone something without knowing how to do it, and yet Guy can teach someone a jutsu. And Kakashi who cannot do the Rasenshuriken, along with Yamato and Asuma who cannot do it, taught Naruto how. So not only can people teach without experience, but Kakashi did in fact have a hand in teaching Naruto the technique.
Naruto didn't figure it out by himself.
Naruto taught Konohamaru Rasengan,thats the required model of teaching a technique,atleats one you fully know...
so compare what i just stated with your own sordid and outrightly fallacious statement of Kakashi teaching Naruto Rasenshuriken
Oh,and please while you are at it,answer my
SIMPLE question
"The Rasenshuriken was invented by Naruto Uzumaki shortly after he figured out the principles of the Wind Release: Rasengan. Like that technique, Naruto typically has the help of two shadow clones in the Rasenshuriken's formation: he provides the chakra, one clone helps keep the chakra contained, and the second clone adds his wind nature. Unlike the Wind Release: Rasengan, additional shape transformation is applied to the Rasenshuriken, creating four large points around the central Rasengan core, giving the appearance of a fūma shuriken. By the time of The Last: Naruto the Movie, Naruto is able to create Rasenshuriken without aid."
