I don't think US Ice Dance is in chaos but I do think that the judging at these Nationals was chaos (and not just in Ice Dance).
Green/Parsons had an off night but so did Chock/Bates and they were held up. Green/Parsons are evenly matched (ability-wise). As much as I admire the improvements that Bratti/Somerville have made, I cannot honestly say that they are evenly matched. Tanith herself boasted that she was so happy to work with a dancer as talented as Ian Somerville (but made no mention of Emily Bratti). If even their own coaches can see they are not evenly matched and are open about this with the Skating Press, then how on Earth are the rest of us supposed to not see it?
I think if the coaches are aware that one partner is not up to the level of the other, it's their job to bring up the skillset of the weaker partner (as we saw at IAM in the partnership of Papadakis/Cizeron). If the Whites are not going to make that a priority then Ian Somerville should move over to solo dance.
If nothing else, the choice to send Bratti/Somerville to Worlds over Green/Parsons just proves what a load of B.S. the whole Body of Work guidelines actually are. After all, when was the last time Bratti/Somerville medalled at a Grand Prix, won Four Continents or placed sixth in their World's debut? When it came to Green/Parsons, BOW was thrown completely out of the window. As Johnny Weir pointed out in his commentary, Ice Dance (especially in the US) is just political.
