Whats the difference? It does maximally matter psychological if its a yellow or white jersey upping the speed before an attack. And I don’t think Pogacar cares too much.But they can't just go mano a mano. Jonas and Pogacar need a strong team to set up an attack. There is a huge difference with Marc Soler setting you up for an attack and peak Sepp Kuss doing that.
The only difference the team can make in the high mountains is chasing back after or act as a relay station - for both use cases Pogacar would have to be dropped before anyway.
The only other one is maybe a bottle or gel and Pogi has some history of underfeeding. But that should be manageable.
Visma is probably going to be stronger, totally see that but not in a way Pogacar has to ride the last 50km of a mountain stage alone and go back to the car to feed and so on.
