If Vingegaard go, we have 4 big names for podium: Pogacar, Vingegaard, Remco and Roglic.
Pogacar is going to get very welll, Rogla came from and injutry, but I rhink he cant progress much more. Remco can progress much and Vingegaard maybe , meybe with some options, but not at last Tour level IMO, if he finally goes. There are another important names, for me especially Carapaz, but the route dont suits him very well this year.
If Vingegaard dont go or it is not at his level there are lot of names into the team to play for a podium...Jorgesson? He is now at his best, the rest can improve...He can do well, it is true, Rogic is not much better than him for one week race...Vingegaard ok is another level...Rogñic is going to improve, so, Jorsesson could do well, but not to win the race.
Kuss? he has been ill, and now is not good...but if he gert his levekl he can do well, I think Better than Jorgesson.
WVA. He is one of the 5 big names of cycling now (maybe in one year we have to put Lazkano there)

The route is no bad for him, He can do very well at GC IMO, but Maybe he would have need an specific preparation for that since the winter.
If Vingegaard is not at his level it will be for Pogacar. Not easy, not like the Giro, but he can put 5 minutes at the second if he want. Remco can do it very well, he will be much stronger in 1 month than now, but it is his first Tour and he has to learn and he will suffer in some mountains.
