Yes, it's not good that the Shibs finished 4th here. But I think the season is still salvageable- it will be a scramble and they'll have to pull deep emotionally and mentally to make a shift again. Which is unfortunate since after the year they had last year I think they were hoping for good stable programs early on that they could gain mileage on for the rest of the season.
However, if they got rid of the SD, perhaps go back to Mary Poppins idea, and then have Alex rest up and then just practice between now and Nationals I think they will still be fine. US has 3 teams again right? If so, I think they can still make a spot.
I don't think we'll see any changes between now and NHK though- one of Alex's tweets seemed to indicate that they would just be traveling abroad from Rostelecom Cup and NHK (it probably didn't make sense to go all the way home again).
Hopefully they'll have a chance to rest between now and NHK and not worry about the programs in this short time period.
