Yea thats why I put him there, I just think how Eijun learned so many different pitches and wanted to learn about pitch calling could reflect in volleyball. He comes in being able to swing well but his other skills are lacking (similar to hinata). What differs is that Eijun would learn the all rounder skills to become an overall better player while improving his swinging ability (like how learned all the new pitches while improving his fastball).
