I wouldn’t say it can’t happen, because this time four years ago we didn’t know anything about Zagitova yet. She was also unremarkable and even at the nationals 2.5 years ago (December 2015) she was only 9th. Let’s not forget that Zagitova has been a decent skater only the last two years - one year in junior and one year in senior. The season before that she wasn’t even good enough to get JGP events! So I don’t think it is any big disaster if her sister is only an average skater at this moment. She definitely has a chance. But so do many other girls. I wouldn’t see her as a big future star yet because the success is also partially caused by luck. Zagitova was lucky that she got invited to test skates even though she had such a bad placement at the nationals the season before. She was lucky she didn’t have any bad day at the test skates (her firsl official test skates) and then she got a JGP events. She was also lucky she didn’t get injured, and that she didn’t have any major body changes this season due to puberty. Many talented girls get stuck with injuries and when they come back, often they may not be as good as before, if they manage to come back at all (e.g. Proklova used to be great!). Whether the stars will align for the younger Zagitova we will have to see. I feel quite sorry for her, actually. Anything she is going to achieve, it will now be taken for granted because her sister already did it, and if she doesn’t achieve as much, she may feel constantly compared to Alina.
