At this point it would have been better to send Aurora Cotop.
i think the reasoning was
1) let her have a chance for redemption as she was sick last year
2) she does have a 3lz-3t... and she did land it at nationals (not perfectly) when the decision was taken.
Aurora is such a beautiful skater but doesn't have all her triples yet... what if she hadn't made the FP? I am okay with Temura going again on second thought....
