The only questionable is Costa IMO. Hirschi, Formolo and Bjerg I have no doubts they'll give their all to support Pogi.
I think this team is thin in the high mountains. In a group of 10-15 best climbers Tadej could be left alone with no support from his teammates. A lot depends on what will be Majka's form and how will Formolo do after having the Giro in his legs. To be honest I don't expect McNulty to be of much help in the mountains. He'll be more useful on the flat and on the hills I think. I might be wrong, though.
But does Pogacar really need so many domestiques in the mountains? He just needs to follow Roglic. When Jumbo start attacking with Kuss or Kruijswijk or even van Aert, come on, we all know they aren't serious. It's all about Roglic for them. If Pogacar can't follow Roglic, then he won't win the Tour, simple.
But personally I'm very surprised de la Cruz is not on the team. I would have expected him to be a key helper. Was this planned from the beginning?
