I suppose an important question is how do you approach the duel with Pogacar? Do you simply let UAE do the work because they are the bigger favourites, and then rely on Roglic just being better than Pogacar (in the time trials and the uphill sprints)? Or do you think you're the physical underdog who needs to race both aggressively and smart as a team to force situations where Pogacar is pressured? For instance with Vingegaard as a co-leader? I think you need to look at the stages very closely and decide what can be done, and then you can make a plan.
Maybe there are stages where you can try to force a selection in the crosswinds for instance, which benefits both van Aert for the intermediate and Roglic for the GC... or something like that. In any case with that monster time trial potential in their team I think they should especially make use of that. Don't bring Affini to the Giro just because he's Italian... But damn, what about Dumoulin? He would be a super good helper on this route... but he doesn't want to be a helper... obviously you either have to bring him as a co-leader... or not at all.
Of course a yellow jersey is more important than a green one, but on the other hand many stages and green with Wout if you go for it (~80%?) seem more likely than yellow with Roglic (like, 30%?)
Then you should probably have a lot of backup plans and be able to improvise as the cobble stage alone could easily lead to a specific situation.
I think at this point in the year you can only have a rough plan anyway, who knows what will happen until then, who will be ill, who will have a break-out year...
Roglic
Vingegaard
van Aert
Teunissen
Dennis
Affini
Kuss
Foss (Dumoulin)
?
I still wonder whether van Aert says these things publically because it's pretty much decided that will happen/ they have promised him... or because they are hesitating to give him support and he wants to pressure them.
