I think it’s because of the way they’ve been shafted this year. Not even a 4CC bid. At their level one’s season doesn’t typically end with US Nationals.
Yeah, I really didn't understand why C/J were shafted, as you said! It was terrible. And after already missing out on Worlds due to the makeup issue when they had some good momentum... But I don't think they are going to give up so easily. I would be very surprised if they didn't come back next season.
