I have no idea how true this is, but rumors had it Caroline is not an easy student. Yes, she spends a lot of time training, but what she actually does may not be the best training habits. I remember an interview where she pretty much stated she didn't do much off ice training, and on ice, she didn't warm up her triples (meaning, didn't do waltz jumps, single-double-triple, went straight to triples). Yes, someone allowed her to get comfortable with her jump technique and didn't make her learn proper technique, didn't demand more speed or better skating skills. Rumor also has it Mama Zhang is not easy to deal with either and a big presence during training time. So, maybe they gang up on the coach?
I hope you are right! I think Mirai has better skating skills and better jump technique than Sasha, so if she is well prepared, when nerves strike, she may loose some of her personality as she goes on auto-pilot, but that is still better than 2 falls. I really think a big piece will be solidifying her jump technique so that URs become a thing of the past. Right now, she still has to think through her jumps, and when nerves creep in, the 1st thing to happen is revert to old habits. We really haven't seen enough of Mirai under pressure to gauge what she's capable of. The most carefree we've seen of her has been at the Olympics this year, and I'd say these Nats 2nd. The year she won Nats, she was petrified for the LP, made some uncharacteristic mistakes, and again at Jr Worlds. But she is still so young! I think switching to Frank has been the best move, one that will see results! I think she will be like Yu-Na is which she can blow the field away with huge scores, and then can afford a less than perfect LP and still win. But I really like to see a Champion who skates very well in both phases.
