I find Chock & Bates improved a lot last season, but I also dont see it happening for them. Hubbell & Donohue are clearly the USFSA favorites, and I dont see that changing. They have not won a world medal since 2016, and while they used to be judges pets and ridiculously held up, they are now the opposite ironically enough. They have only even made top 5 in 1 of the last 4 Worlds/Olympics and that was at the typically watered down post Olympic Worlds where they managed 5th. I was optimistic for them as possible medalists at Worlds after their big Four Continents win, but the judges were lukewarm on them at Worlds despite skating well, even placing a subpar W&P (in the FD anyway) over them. While Hubbell & Donohue rebounded from the big Four Continents loss to medal even with their blah Romeo & Juliet, and firmly solidy themselves as still U.S #1. It is hard to imagine H&D to come up with worse vehicles and programs for themselves than last season, and C&B with the best work I ever saw from them still could not turn the tables on them. I think despite the great improvements they made in Montreal, Chock & Bates have a HUGE challenge to win another world medal before their probable retirement in 2022, never mind challenging P&C.
Of course who knows, if Hubbell & Donohue have another dissapointing season and C&B can continue the improvement they made last year in Montreal the USFSA might rethink things. And there is still the question if the Shibutanis return (I dont think they will, but it isnt impossible until we are less than a year from the Olympics and there is no talk of it). Regardless one thing is for sure, only the clear U.S #1 can even think of challenging Papadakis & Cizeron, and it will take amazing programs and improvement from any of them to do so. The same is probably true of the top Russian teams, only the Russian #1 (right now Sinitsina & Katsalapov having the clear edge there over Stepanova & Bukin) can even think of challenging P&C.
