If he's sacrificed some explosiveness to get stronger in longer climbs, his race programme makes no sense?
Why focus the spring calendar on Paris Nice and Basque country? These are the most hilly and explosive WT stage races.
I saw Roglic complaining about the cold weather here in this Paris Nice. His fans say he is much better in heat. Well, paris nice and Basque Tour are cool, wet or windy races, the worst of the spring.
He said he is here in Paris Nice to get used to teammates, the team, equipment. If he want to get used to equipment and teammates, he could have gone to Algarve or UAE tour. In Uae it would be nice and warm with a time trial, in Algarve low stress with a long time trial. These would be an ideal races to get used to the team. There is not TTT in le tour, there is no reason to come to Paris Nice for that.
After UAE or Algarve he could then go to altitude to prepare Cataluña, Liege and Romandie. These races suit much better the guys who are strong in the long climbs, would be better opportunities to test the legs. Catalunya is warmer as well, a nice option.
Even Tirreno would be better than Paris Nice, because Tirreno has the long climbs and an ITT. He could race with hindley, who will be much more present in the high Mountains of Le tour than Vlasov. He could also do Strade Bianche to practice the gravel, certainly would be better option for the team, than dani Felipe Martinez.
He should at least be the favourite for fleche wallonnie
