They already train part time with Igor and Pasquale at Novi in Detroit. Igor was in the Kiss n Cry with them at Worlds.Seems like Igor would be available, as he no longer has any top teams and they are already working with him for choreography. He has his pros and cons but he is a good technical coach and doesn't have the one big con that Morozov has.
They were in Novi for a stretch prior to Worlds. Yura Min and others were posting videos of Andrew getting cake and balloons at the rink for his birthday.
Seems like a good arrangement as they can get the benefit of Igor/Pasquale's coaching but also be able to maintain a home base in New Jersey (which I understand they like a lot).
