If it's true that Mishin was willing to give one coach spot to someone else, I really don't see a problem. I wouldn't see it as a problem if any other federation did that either.I think people are more salty about TT bringing more coaches than skaters.
In all the other cases; Hamada, Lambiel, Orser, etc they all have more students. Hamada has Satoko, Rika. Lambiel has Denis, Rika, Shoma. Orser has Hanyu and Cha. While TT only have two skaters.
