They themselves came out and said that it was their tactic to not have him ride, because they "had riders close to the front" and wanted to increase their chances to win the stage with 3, rather than 1 rider. Poitschke made the decision.
I see. Yes, I don't think that is what @QueenStagiaire meant, I for sure was refering to sprints that are punchy and come after a normal run in for sprints we are used to that Pogacar wins. There should be no surprise there.
You'd have to ask Enrico Poitschke, he is the one who made the decision yesterday in the car. It makes really little sense to me, and I don't want to believe that Roglic is so insecure that you have to do that, to somewhat keep him happy.
