Who would you say are done with their scoring opportunities? I'll give you Simon Yates, who probably won't do that much after a double GT, apart from maybe a cameo or two in Italian autumn classics. But other than that, I can't see the program of most of his other riders hampering them too much. Even Arensman, who's also doing his 2nd GT at the moment, might well show up in some Tour de Luxembourg-ish race towards the end of the season and do quite well.
Hindley, Ciccone, Almeida and probably Gall still have the Vuelta and potentially Italian classics, especially Ciccone. Vine surely has more to do this season, even as a leader in smaller stage races probably.
Now sure, Vingegaard and Van Aert and Ayuso might have more scoring left to do compared to those mentioned, but the gap is huge and there's no guarantee they will set the world alight everywhere either.
We still kind of agree here, as both of us find it difficult to see how Salvarani gets caught, but I don't think it's an absolute given that the overall scoring for the rest of the season will be so much lower than EITB's formula predicts. Maybe most riders bar Vingegaard won't win a GT or WC or something like that, but I don't think that has happened in all data points from the other seasons either.
There are also still a lot of riders who at the start of the season seemed like good picks who haven't really gotten going yet (if they ever will is another question of course). From my own team I can mention Staune-Mittet, Penhoët, Riccitello, Blobloblo, Lafay, Nordhagen, De Schuyteneer, Bax, Bisiaux, Louvel, Gloag, Torres, Kron. Surely not all of them will continue to bomb the entire season when there are more than three months and a lot of smaller races left. Could also add the likes of Kamp, Vader and Sénéchal to that list, but they are more in the category of will probably never get going.
