Haven't they been getting choreography elsewhere, though? They've worked with those DWTS people this season on their SD and Michael Jackson's choreographers for their FD. The season prior, they worked with a DWTS person and the choreographer who worked on the film Memoirs of a Geisha. Are those people just collaborators with Marina being the main choreographer?
Maybe they need less outside dance folk and get some choreographers who know how to choreograph on the ice.
