Pogacar can't win this jersey. Intermediate sprints give a lot of points.
I have checked the intermediate sprints and they are almost all placed on flat roads or on the beginning of the stages, including on the mountain ones, meaning that the sprinters shouldn't have too much trouble grabbing lots of points on those. If anything, this looks like a great opportunity for Van der Poel to fight for the green jersey for once in his career, but with Philipsen being there, I think the latter is more likely to win it.
For Pogacar to win the green jersey, I think three conditions will need to be fulfilled:
- Lack of a dominant sprinter during the race
- Winning at least 5-6 stages
- Winning at least one 50 point stage
Its going to be difficult but not impossible given its Pogacar we are talking about.
