I'm honestly surprised so many here think this move is a good idea for Marin. Again, I don't wish her anything bad and hopefully I'm wrong, but... Her skating skills actually regressed this season compared to last, and now she switches to someone who literally said stuff like "one foot skating, two foot skating, where's the difference?" and as far as I remember only has skaters with mediocre SS that haven't improved under him at all. Transitions is also a word he's never heard before I guess. He might be able to help Marin with her jumps, get them rotated and more consistent - but how high are the chances that that will be enough? Japan has several girls who are quite consistent, most of them can land jumps with better quality (and it's not as if any of Rafs skaters had jumps with great quality). And most of these girls are only improving in PCS and seem to be on upward trends. I have to admit I'm not sure where else I would have put her that feels ideal to me, but Raf is very, very, very far down the list. Heck I'd sent Marin to Waka's coach I really want her away from before Raf.
But well, nothing I can do. Good luck Marin and proof me wrong please!
