Because Julia didn't win the gold medal in ledies, and she desperately needs in a world medal. She and her coach are very ambitious, and at the same time Etery has never been a big athlete herself. She doesn't have her own expirience how your mind and body react to participation in highest level of competitions, and didn't test it as a coach. I think Julia is overloaded by high expectations. Her fifth on OG was counted as unsatisfactory result, and nobody from her team is thinking that fifth could be her place even in the case of a clean skating. Only time will show is this strategy of pushing young athlets ahead despite of tiredness and injuries is right or wrong...n
