Remco and Roglic will also be in the Tour, it will not be that easy, even without the presence of Vingegaard.
The truth is Pogacar is a very talented rider, but also one of the most lucky riders(luck merchant like someone said here), because he almost never face the top riders in the races he won in the last year, but also this year. For some reason he almost never faces Van der Poel, Roglic, Remco, or Vingegaard, and when he faces them he wins way way less, and sometimes gets absolutely annihilated, like he was by Vingegaard in the TOUR, Van der Poel in the worlds, and also Evenepoel in the Worlds 2022.
When was the last time Pogacar faced Roglic in a one week race? I really don't remember. Pogacar chooses very well the calendar and unfortunately, Van aert, Remco, Vingegaard, Remco and Roglic in the last years, had really bad luck.
The crash by Remco in 2020, was a shame, because Pogacar would had a lot of trouble in one day races against him.
If we look at pure power, there is some riders like Vingegaard and Remco who can push more watts than Pogacar.
