Yes they are. Both Gabby (1 JGP bronze) and Kaetlyn (10th at JW) didn't exactly light the world on fire as juniors.Canadian women late bloomers then perhaps. I'm a big fan of Kaetlyn but have no idea what she did as a junior.
Anyway, as a casual follower of the Russian ladies, the pushing of Konstantinova makes 0 sense to me. They have many other ladies who are more talented, more consistent, and would do well having more experience.
