Heyo, Russian-speaking schaatsfan here. Based on a certain article, the reason why Kuzin didn't make it to the national team is not his lack of discipline. Kuzin himself claims the following, quoted: "I don't really know why it happened to be this way. Probably, it happened due to my unwillingness to train under the guidance of our [national team's] new coach Dmitry Babenko. We have been skating side by side for many years. He has always been a stayer and has never skated any sprint. On the other hand, I have never had anything to do with long distances. We had a talk and came to the conclusion that we should part our ways. I think this was the main reason why I had been fired. I thought I'd stay. There is a certain practice when an athlete is training separately from the rest of the team and joins it in the aftermath. However, it seems like it is not the case for speed skating. It means, if I refuse to train with our national coach, I'm out of the team. <...> There is a law [in Kazakhstan] that the national champion cannot be excluded from the national team. <...> Dmitry is a young and ambitious coach. Everyone is talking about some kind of "conflict" that I had with him but I can't call it a conflict. We had a certain miscommunication but the officials perceived it as a signal for action and quickly excluded me from the team". Hope this will be helpful for everyone.
